Thai/Russian langauge support

[Manas]

In my application i use metadraw control to show floorplan and
building information. My application can support many asian languages.
When i change my system language to "Thai" or "Russian" & try to show
some text using metadraw control, the Thai/Russian charaters are shown
as invalid junk chatacters. I used below mentioned code to set
metadraw fontcharset and fontname for Thai language. Still it doesnot
work.

MDraw.FontCharSet = Character_Set.MyCharSet
MDraw.FontName = Character_Set.MyCharName

Please let me know the code change or any property settings to support
Thai & Russian language.

Yor help on this will be appreciated.

Thanks
Manas
