I'm surprised you get a long list for such a minority language - my system only has "Khmer OS System", which I installed specifically for Khmer support. >> I doubt that has OTF tables for Khmer - try a Khmer specific font (I >> have one installed called "Khmer OS System") Actually, it must have some otf tables for khmer, as it is one of the fonts recommended for viewing of Khmer here (though prefixed with "quick and dirty"): http://www.bauhahnm.clara.net/Khmer/Welcome.html Now that I've tried your original report on both GNU/Linux and Windows, I see the bug on Windows. It may be due to the version of usp10.dll - I remember when I originally worked on the uniscribe code, I had to upgrade usp10.dll manually to get support for some languages - Tibetan and Sinhalese I specifically remember, but there may have been others. But according to info I've found, the last update to usp10.dll was shipped as part of XP SP2, bringing Khmer support amongst others, so there may be another bug here, or just a difference in the way uniscribe maps glyphs compared to libotf which affects Khmer (and I think Burmese) but not the Indic scripts. Also, according to this page: http://www.microsoft.com/typography/otfntdev/khmerot/features.aspx the following otf gsub features are required to properly display Khmer: pref blwf abvf pstf pres blws abvs psts clig So the following might be a better font spec, at least for Windows: (font-spec :registry "iso10646-1" :otf '(khmr nil (pref blwf abvf pstf pres blws abvs psts clig))) ^ permalink raw reply [flat|nested] 14+ messages in thread

Moving the cursor on the Khmer list, the cursor appears as wide as the character it is upon (i.e., is very small but perfectly visible over U+179A KHMER LETTER RO), and neither forward nor backward movement shows anything unexpected.

This may be part of the problem Eli is seeing, but I also see display corruption (cursor being left behind) when moving backwards through Khmer text, so there is probably also a problem with the version of usp10.dll on Windows XP. > As for the bug, I don't see it either.

There, the cursor moves over groups of characters, so even on versions of uniscribe that fully support Khmer fonts, the behaviour is still different than libotf. ^ permalink raw reply [flat|nested] 14+ messages in thread

It is still present in Emacs 26.3 with the Uniscribe font backend, but not in Emacs 27 with HarfBuzz. So I'm closing the bug, as HarfBuzz is our default font backend.
