Hi All
Can I clear any doubt on Burmese Localization Situation.
*anyone can use any myanmar Unicode 5.1 - compliant font to look at it.*
For Burmese, It's different from English situation. Microsoft Windows XP and older operating system are widely used by Burmese People. Microsoft Windows Vista natively support Burmese Rendering. Ubuntu 8.04 natively support Burmese Rendering. Main Problem is lack of rendering support by Microsoft Windows older version. We have to patch/update Uniscribe Rendering Engine in older Operating System. That's technical issues.
My current understanding is that
usp10.dll is protected by Microsoft's EULA which prohibits copying
usp10.dll onto a computer. Some developers can license usp10.dll but
only for local use with their application, the license prohibts them
from replacing the system version of usp10.dll
There are also issues with font fallback mechanisms. As Michael
pointed out, you'd have disasterous results if the fallback selected a
pre-Unicode 5.1 font implementation.
In theory a user could
select a default font for a script in their web browser's
preferences/options. A few barriers exist. Firefox has no UI mechanism
to select to specify a default Myanmar script font. Selecting a default
font in the Windows version of Internet Explorer is inhibited due to a
long standing bug in mlang.dll, IE will not recognise a Myanmar Script
font. The only remedy is to edit the Windows registry. A task that the
average user may not be able to perform.
The only real solution is to handle font fall back through CSS,
identifying the most suitable and most commonly available of the
Unicode 5.1 fonts and specifying each within a CSS rule.
