+ * 				   result might be different.
+ * 				   On the flip side, it means that when this

+ * 				   cluster, and the two sides will represent the
+ * 				   exact same result one would get if breaking
+ * 				   input text at the beginning of this cluster
+ * 				   and shaping the two sides separately.
+ * 				   This can be used to optimize paragraph
+ * 				   layout, by avoiding re-shaping of each line
+ * 				   after line-breaking.
+ * @HB_GLYPH_FLAG_UNSAFE_TO_CONCAT: Indicates that if input text is changed on one
+ * 				   side of the beginning of the cluster this glyph
+ * 				   is part of, then the shaping results for the
+ * 				   other side might change.
+ * 				   Note that the absence of this flag will NOT by
+ * 				   itself mean that it IS safe to concat text.
+ * 				   Only two pieces of text both of which clear of
+ * 				   this flag can be concatenated safely.
+ * 				   This can be used to optimize paragraph
+ * 				   layout, by avoiding re-shaping of each line
+ * 				   after line-breaking, by limiting the
+ * 				   reshaping to a small piece around the
+ * 				   breaking positin only, even if the breaking
+ * 				   position carries the
+ * 				   #HB_GLYPH_FLAG_UNSAFE_TO_BREAK or when
+ * 				   hyphenation or other text transformation
+ * 				   happens at line-break position, in the following
+ * 				   way:
+ * 				   1. Iterate back from the line-break position
+ * 				   until the first cluster start position that is
+ * 				   NOT unsafe-to-concat, 2. shape the segment from
+ * 				   there till the end of line, 3. check whether the
+ * 				   resulting glyph-run also is clear of the
+ * 				   unsafe-to-concat at its start-of-text position;
+ * 				   if it is, just splice it into place and the line
+ * 				   is shaped; If not, move on to a position further
+ * 				   back that is clear of unsafe-to-concat and retry
+ * 				   from there, and repeat.
+ * 				   At the start of next line a similar algorithm can
+ * 				   be implemented. That is: 1. Iterate forward from
+ * 				   the line-break position until the first cluster
+ * 				   start position that is NOT unsafe-to-concat, 2.
+ * 				   shape the segment from beginning of the line to
+ * 				   that position, 3. check whether the resulting
+ * 				   glyph-run also is clear of the unsafe-to-concat
+ * 				   at its end-of-text position; if it is, just splice
+ * 				   it into place and the beginning is shaped; If not,
+ * 				   move on to a position further forward that is clear
+ * 				   of unsafe-to-concat and retry up to there, and repeat.
+ * 				   A slight complication will arise in the
+ * 				   implementation of the algorithm above,
+ * 				   because while our buffer API has a way to
+ * 				   return flags for position corresponding to
+ * 				   start-of-text, there is currently no position
+ * 				   corresponding to end-of-text.  This limitation
+ * 				   can be alleviated by shaping more text than needed
+ * 				   and looking for unsafe-to-concat flag within text
+ * 				   clusters.
+ * 				   The #HB_GLYPH_FLAG_UNSAFE_TO_BREAK flag will
+ * 				   always imply this flag.
+ *				   To use this flag, you must enable the buffer flag
+ *				   @HB_BUFFER_FLAG_PRODUCE_UNSAFE_TO_CONCAT during
+ *				   shaping, otherwise the buffer flag will not be
+ *				   reliably produced.
+ * 				   Since: 4.0.0
+ * @HB_GLYPH_FLAG_SAFE_TO_INSERT_TATWEEL: In scripts that use elongation (Arabic,
+				   Mongolian, Syriac, etc.), this flag signifies
+				   that it is safe to insert a U+0640 TATWEEL
+				   character before this cluster for elongation.
+				   This flag does not determine the
+				   script-specific elongation places, but only
+				   when it is safe to do the elongation without
+				   interrupting text shaping.
+				   Since: 5.1.0
