FYI:
There're an open issue regarding grapheme-cluster boundaries in Thai.
* SARA AM as an Other_Grapheme_Extend?
Whether "0E33;THAI CHARACTER SARA AM" should be a GraphemeExtend
character or not?
By Unicode definition, SARA AM is an Lo, not a combining
character. But many Thai applications (MS Office/ Windows/
OpenOffice.org) treats SARA AM like a combining character (unlike SARA
AA), i.e. cursor always jump over it. Whether this is right or not is
controversial but the fact is that Windows users are used to it.
My personal question is that, if it is favorable for Thai to treat
SARA AM as part of the previous grapheme cluster, is it possible for
UTC to consider adding SARA AM as an Other_Grapheme_Extend?
--- I also notice that Grapheme_Link is removed from the grapheme-cluster definition. This is appropriate for Thai because PHINTHU should not cause two grapheme clusters to be linked together.-- Feel free to disclose the contents of this message.
