I have upgraded to Windows 7 from XP.
Earlier, Arial Unicode MS used to be the comprehensive Font set for all Indian Languages. Now after upgrading, I find this Font set (Arial Unicode MS) gives wrong results for Indian Language Fonts - particularly Tamil and Malayalam.
In fact Arial Unicode MS was 'hidden' in the font set - I had to change it to 'show'.
I have tried other fonts, but the glyphs are not properly implemented therein.
I use unicode with Notepad. But, I am unable to exercise compatibility to previous versions of Windows. Even if I do, I seem to have lost earlier Arial Unicode MS version.
