Firebird INTL
=============

Author: Adriano dos Santos Fernandes <adrianosf at uol.com.br>


Architecture
------------

Firebird allow you to specify character sets and collations in every field/variable declaration.
You can also specify the default character set at database create time and every CHAR/VARCHAR
declaration that omits the character set will use it.

At attachment time you can specify the character set that the client want to read all the strings.
If you don't specify one, NONE is assumed.

There are two specials character sets: NONE and OCTETS.
Both can be used in declarations but OCTETS can't be used in attachment.
They are very similar with the exception that space of NONE is ASCII 0x20 and space of OCTETS
is 0x00.
They are specials because they don't follow the rule of others character sets regarding conversions.
With others character sets conversion is performed with CHARSET1->UNICODE->CHARSET2. With
NONE/OCTETS the bytes are just copied: NONE/OCTETS->CHARSET2 and CHARSET1->NONE/OCTETS.


Enhancements
------------


	Well-formedness checks
	----------------------

	Some character sets (specially multi-byte) don't accept everything.
	Now, the engine verifies if strings are wellformed when assigning from NONE/OCTETS and strings
	sent by the client (the statement string and parameters).


	Uppercase
	---------
	
	In FB 1.5.X only ASCII characters are uppercased in character sets default collation order
	(without collation specified). Ex:
	
	isql -q -ch dos850
	SQL> create database 'test.fdb';
	SQL> create table t (c char(1) character set dos850);
	SQL> insert into t values ('a');
	SQL> insert into t values ('e');
	SQL> insert into t values ('á');
	SQL> insert into t values ('é');
	SQL> 
	SQL> select c, upper(c) from t;

	C      UPPER
	====== ======
	a      A
	e      E
	á      á
	é      é

	In FB 2.0 the result is:
	
	C      UPPER
	====== ======
	a      A
	e      E
	á      Á
	é      É


	Maximum string length
	---------------------

	In FB 1.5.X the engine doesn't verify logical length of MBCS strings.
	Hence a UNICODE_FSS field can accept three (maximum length of one UNICODE_FSS character) times more characters than what's declared in the field size.
	For compatibility purpose this was maintained for legacy character sets but new character sets (UTF8, for example) don't suffer from this problem.


	NONE as attachment character set
	--------------------------------
	
	When NONE is used as attachment character set, the sqlsubtype member of XSQLVAR has the character set number of the read field, instead of always 0 as in previous versions.
	
	
	BLOBs and collations
	--------------------
	
	Allow usage of DML COLLATE clause with BLOBs. Ex:
	select blob_column from table where blob_column collate unicode = 'foo';
	
	
New character sets and collations
---------------------------------


	UTF8 character set
	------------------

	The UNICODE_FSS character set has a number of problems: it's an old version of UTF8, accepts
	malformed strings and doesn't enforce correct maximum string length. In FB 1.5.X UTF8 it's an
	alias to UNICODE_FSS.
	Now UTF8 is a new character set, without these problems of UNICODE_FSS.


	UNICODE collations (for UTF8)
	-----------------------------
	
	UCS_BASIC works identical as UTF8 without collation specified (sorts in UNICODE code-point order).
	UNICODE sorts using UCA (Unicode Collation Algorithm).
	Sort order sample:
	
	isql -q -ch dos850
	SQL> create database 'test.fdb';
	SQL> create table t (c char(1) character set utf8);
	SQL> insert into t values ('a');
	SQL> insert into t values ('A');
	SQL> insert into t values ('á');
	SQL> insert into t values ('b');
	SQL> insert into t values ('B');
	SQL> select * from t order by c collate ucs_basic;
	
	C
	======
	A
	B
	a
	b
	á
	
	SQL> select * from t order by c collate unicode;
	
	C
	======
	a
	A
	á
	b
	B
	
	
	Brazilian collations
	--------------------

	Two case-insensitive/accent-insensitive collations were created for Brazil: PT_BR/WIN_PTBR
	(for WIN1252) and PT_BR (for ISO8859_1).
	Sort order and equality sample:

	isql -q -ch dos850
	SQL> create database 'test.fdb';
	SQL> create table t (c char(1) character set iso8859_1 collate pt_br);
	SQL> insert into t values ('a');
	SQL> insert into t values ('A');
	SQL> insert into t values ('á');
	SQL> insert into t values ('b');
	SQL> select * from t order by c;
	
	C
	======
	A
	a
	á
	b
	
	SQL> select * from t where c = 'â';
	
	C
	======
	a
	A
	á


Drivers
-------

New character sets and collations are implemented through dynamic libraries and installed in the server with a manifest file in intl subdirectory. For an example see fbintl.conf.
Not all implemented character sets and collations need to be listed in the manifest file. Only those listed are available and duplications are not loaded.

After installed in the server, they should be registered in the database's system tables (rdb$character_sets and rdb$collations).
One script file with stored procedures to register/unregister is provided in misc/intl.sql.

In FB 2.1, don't use misc/intl.sql for collations anymore, now a DDL command exists for this task.

Syntax:
	CREATE COLLATION <name>
		FOR <charset>
		[ FROM <base> | FROM EXTERNAL ('<name>') ]
		[ NO PAD | PAD SPACE ]
		[ CASE SENSITIVE | CASE INSENSITIVE ]
		[ ACCENT SENSITIVE | ACCENT INSENSITIVE ]
		[ '<specific-attributes>' ]

Notes:
	1) Specific attributes should be separated by semicolon and are case sensitive.

Examples:
	1) CREATE COLLATION UNICODE_ENUS_CI
			FOR UTF8
			FROM UNICODE
			CASE INSENSITIVE
			'LOCALE=en_US';

	2) CREATE COLLATION NEW_COLLATION
			FOR WIN1252
			PAD SPACE;
		-- NEW_COLLATION should be declared in .conf file in $root/intl directory


ICU character sets
------------------

All non-wide and ascii-based character sets present in ICU can be used by Firebird.
But for small distribution kit, we customize ICU to include only essential character sets or the
ones we had feature request.
If the character set you need is not included in it, you can replace ICU libraries by a complete
one found in our site or installed in your OS.

To use, you first need to register it in intl/fbintl.conf as follow:
	<charset NAME>
		intl_module	fbintl
		collation	NAME [REAL-NAME]
	</charset>

And register it in the databases using sp_register_character_set (found in misc/intl.sql).
You need to know how much bytes a single character can occupy in the encoding.

Example:
	<charset GB>
		intl_module	fbintl
		collation	GB GB18030
	</charset>

	execute procedure sp_register_character_set ('GB', 4);


UNICODE collation
-----------------

You can use unicode collation (case sensitive and case insensitive) in all character sets present
in fbintl.
They're already registerd in fbintl.conf, but you need to register in the databases you want with
the attributes you desire.
They should use this name convention: charset_collation. Ex:
	create collation win1252_unicode
		for win1252;
	create collation win1252_unicode_ci
		for win1252
		from win1252_unicode
		case insensitive;

Note the name should be as in fbintl.conf (i.e. ISO8859_1 instead of ISO88591, for example).


Specific attributes
-------------------

Note that some attributes may not report error but not work with some collations.

DISABLE-COMPRESSIONS: Disable compressions (aka contractions) changing the order of a group of characters.
Valid for: collations of narrow character sets.
Format: DISABLE-COMPRESSIONS={0 | 1}
Example: DISABLE-COMPRESSIONS=1

DISABLE-EXPANSIONS: Disable expansions changing the order of a character to sort as a group of characters.
Valid for: collations of narrow character sets.
Format: DISABLE-EXPANSIONS={0 | 1}
Example: DISABLE-EXPANSIONS=1

ICU-VERSION: Specify what version of ICU library will be used. Valid values are the ones defined in
the config file (intl/fbintl.conf) in entry intl_module/icu_versions.
Valid for: UNICODE collations.
Format: ICU-VERSION={default | major.minor}
Example: ICU-VERSION=3.0

LOCALE: Specify the collation locale.
Valid for: UNICODE collations.
Requires: Complete version of ICU libraries.
Format: LOCALE=xx_XX
Example: LOCALE=en_US

MULTI-LEVEL: Uses more than one level for ordering purposes.
Valid for: collations of narrow character sets.
Format: MULTI-LEVEL={0 | 1}
Example: MULTI-LEVEL=1

SPECIALS-FIRST: Order specials characters (spaces, symbols, etc) before alphanumeric characters.
Valid for: collations of narrow character sets.
Format: SPECIALS-FIRST={0 | 1}
Example: SPECIALS-FIRST=1


NUMERIC-SORT: Specify how numbers are sorted.
Valid for: UNICODE collations.
Format: NUMERIC-SORT={0 | 1} (0 is the default)

NUMERIC-SORT=0 sorts number in alphabetic order. Example:
1
10
100
2
20

NUMERIC-SORT=1 sorts number in numeric order. Example:
1
2
10
20
100


Collation changes
-----------------

ES_ES (as well as new ES_ES_CI_AI) collation automatically uses attributes DISABLE-COMPRESSIONS=1;SPECIALS-FIRST=1.
The attributes are stored at database creation time, so databases with ODS < 11.1 do not use it.
