It's quite likely that there's a small fix required for get the hinting mapping
the same as the pango/gtk one, autohint vs non auto-hint hinting type or
something like that, but is there a rpm available with "Malgun Gothic" in it ?
Or where does it come from.

Comment 3 sangu 2006-05-15 10:12:20 UTC
Malgun gothic is MS Vista new default Korean font.

Comment 5 Caolan McNamara 2006-05-18 09:43:49 UTC
sangu: Can your hinting issue be reproduced (in devel) with any fonts available
for me to test with? Malgun Gothic is not available unless I have windows vista,
which I don't of course :-)

Comment 6 Caolan McNamara 2006-05-22 09:34:10 UTC
I'd love to be able to fix this, is there any other font that causes a similiar
problem that I could work with ?

Comment 7 Caolan McNamara 2006-05-22 13:18:43 UTC
I think I've identified the problem, I have a similiar looking problem with
"Bitstream Charter"

Comment 8 sangu 2006-05-26 03:44:06 UTC
Sorry about delay response.

This problem still happens in openoffice.org-core-2.0.3-3.2

This url is malgun gothic.


Using Meiryo for Japanese, Microsoft JhengHei for Chinese (Traditional),
Microsoft YaHei for Chinese (Simplified), this same problem will happen, maybe.

The fonts are cjk fonts which include cleartype(subpixel) and hinting.

Comment 9 Caolan McNamara 2006-05-26 12:42:56 UTC
I see this (other problem) now I think, GF_UNHINTED is hardcoded against not
having the TT BYTECODEINTERPTER available at compile time

    // #95556# autohinting not yet optimized for non-western glyph styles
    &&  ( (aChar >= 0x0600 && aChar < 0x1E00)   // south-east asian + arabic
        ||(aChar >= 0x2900 && aChar < 0xD800)   // CJKV
        ||(aChar >= 0xF800) ) )                 // presentation + symbols
        nGlyphFlags |= GF_UNHINTED;

got a new fix for that now...
