No, it does not ;-)

andLinux on W32 is wonderful, no more cygwin etc.

One example:

The following comes out correctly in Unipad, also in Opera's email  
composer (don't know how it will look in your client). It does not come  
out right in Windows Notepad or in gedit. Kate does get it right (and  
other kde apps as well), as well as OOo:

==============
European:
18%, 1--3

Arabic:
١٨٪، ١--٣

Farsi:
۱۸٪، ۱--۳
==============

See attached as well.

Unipad is designed as a complete unicode utility, and has lots of other  
nifty features as well, especially for editing Arabic script. Its  
Arabic-script editing features are truly unique and useful. Eg, I  
select/edit vowels horizontally not vertically.

Unipad has:

Char Info bar:
character code value (U+0000)
character name (if assigned)
character category (letter, decimal digit, etc.)
character block (script, collection, etc.)

Extended Char Info bar:
decimal character code value
encoded byte sequence (octals)
bidirectional character type
decimal digit value (only if the character represents a decimal digit)

Unipad is not a good choice for a programmer's or TeX editor, but in  
overall unicode editing it is unrivalled, although it has not been updated  
since Unicode 4.1.0 :-(

Best wishes
Idris
