    { Read languages:

      0. Determine final code pages:
      Unicode Setup uses Unicode text and does not depend on the system code page. To
      provide Setup with Unicode text without requiring Unicode .isl files (but still
      supporting Unicode .iss, license and info files), the compiler converts the .isl
      files to Unicode during compilation. It also does this if it finds ANSI plain text
      license and info files. To be able to do this it needs to know the language's code
      page but as seen above it can't simply take this from the current .isl. And license
      and info files do not even have a language code page setting.

      This means the Unicode compiler has to do an extra phase: following the logic above
      it first determines the final language code page for each language, storing these
      into an extra list called PreDataList, and then it continues as normal while using
      the final language code page for any conversions needed.

      Note: it must avoid caching the .isl files while determining the code pages, since
      the conversion is done *before* the caching.

      1. Read Default.isl messages:

      ReadDefaultMessages calls EnumMessages for Default.isl's [Messages], with Ext set to -2.
      These messages are stored in DefaultLangData to be used as defaults for missing messages
      later on. EnumLangOptions isn't called, the defaults will (at run-time) be displayed
      using the code page of the language with the missing messages. EnumMessages for
      Default.isl's [CustomMessages] also isn't called at this point, missing custom messages
      are handled differently.

      2. Read [Languages] section and the .isl files the entries reference:

      EnumLanguages is called for the script. For each [Languages] entry its parameters
      are read and for the MessagesFiles parameter ReadMessagesFromFiles is called. For
      each file ReadMessagesFromFiles first calls EnumLangOptions, then EnumMessages for
      [Messages], and finally another EnumMessages for [CustomMessages], all with Ext set
      to the index of the language.

      All the [LangOptions] and [Messages] data is stored in single structures per language,
      namely LanguageEntries[Ext] (langoptions) and LangDataList[Ext] (messages), any 'double'
      directives or messages overwrite each other. This means if that for example the first
      messages file does not specify a code page, but the second does, the language will
      automatically use the code page of the second file. And vice versa.

      The [CustomMessages] data is stored in a single list for all languages, with each
      entry having a LangIndex property saying to which language it belongs. If a 'double'
      custom message is found, the existing one is removed from the list.

      3. Read [LangOptions] & [Messages] & [CustomMessages] in the script:

      ReadMessagesFromScript is called and this will first call CreateDefaultLanguageEntry
      if no languages have been defined. CreateDefaultLanguageEntry first creates a language
      with all settings set to the default, and then it calles ReadMessagesFromFiles for
      Default.isl for this language. ReadMessagesFromFiles works as described above.
      Note this is just like the script creator creating an entry for Default.isl.

      ReadMessagesFromScript then first calls EnumLangOptions, then EnumMessages for
      [Messages], and finally another EnumMessages for [CustomMessages] for the script.
      Note this is just like ReadMessagesFromFiles does for files, except that Ext is set
      to -1. This causes it to accept language identifiers ('en.LanguageCodePage=...'):
      if the identifier is set the read data is stored only for that language in the
      structures described above. If the identifier is not set, the read data is stored
      for all languages either by writing to all structures (langoptions/messages) or by
      adding an entry with LangIndex set to -1 (custommessages). This for example means
      all language code pages read so far could be overwritten from the script.

      ReadMessagesFromScript then checks for any missing messages and uses the messages
      read in the very beginning to provide defaults.

      After ReadMessagesFromScript returns, the read messages stored in the LangDataList
      entries are streamed into the LanguageEntry.Data fields by PopulateLanguageEntryData.

      4. Check 'language completeness' of custom message constants:
      CheckCustomMessageDefinitions is used to check for missing custom messages and
      where necessary it 'promotes' a custom message by resetting its LangIndex property
      to -1. }
