Dear Perter, Members
I would like to share about burmese issues relating Uniscribe.
The Latest Uniscribe Ver 1.606.5095.0 supported to shape burmese character
in lastest Windows 2000 and Windows XP. In OpenType Table (rlig and kern)
features supported render burmese characters according to unicode encoding.
But burmese scripts are complex script type and we needed to handle
reordering, fallback rendering, cursor movement and word breaking by
uniscirbe engine. AFAK, MS needs to implement script specific function on
uniscribe. It mean everybody said so *Burmese language not supported*,
right?
And Do we need others setting/implementation for Burmese? I mean NLS data,
Locale setting and code page. We have a doubt that somebody said *no need to
implement for specific language*, For every language, Microsoft will
support Microsoft Locale Builder in next version of vista, is it true for
burmese? I guess so Microsoft can't support rendering engine customization
in locale builder. I saw this screenshots in
http://blogs.msdn.com/photos/shawnste/images/535611/original.aspx
But Some of Burmese language implementer announced that "Their OpenType Font
& Unicoded implementation succeeded in Microsoft Windows." We do not accept
condition that OpenType font might be succeeded but uniscribe and input
method are needed to implement by Microsoft. ref:
http://www.mymyanmar.net/ota.php *you may see some graphics* (it's wrote
down by burmese langauge) So, Please sujjest me that implementation is
suitable for long term use. Any how, We need to use for that kinds of
implementation, if MS does not implement for burmese.
Their implementation might be faced some problem when new version of
uniscribe implementation for burmese by Microsoft. May be double reordering
and some infinite loops in rendering.
And Let me know basis functions of uniscribe for complex script. We would be
avoid some implementation in fonts. We are going to enable Burmese for pango
and qt rendering engine. It would be release in next month. So, we can
express opentype specification for burmese when succeeded in pango/qt
modules.
Regards
Ngwe Tun
