Thanks alot Tony. Very valuable information. Meantime I created my
own function to convert strings built from ANSI + Cyrillic characters
encoded in UTF-8 to windows-1251 (Cyrillic-window). My site is using
either cyrillic or latin characters so that should be enough and I
tested it seems to work fine. However, I wanted to be on the safe
side and use something provided in ASP so I will research carefully
your suggestion and change my solution accordingly. Can't help to
notice though how easy this is done in PHP with just a single
function, which if I am not mistaken also exists in other webdev
languages.
One more thing: you said "Basically if your not using any strange
character, then you should be able
>; to just dump the data into a string, and ASP will do it for you."
what do you mean by that?
If I am using only ANSI chars (with ascii < = 127 ) then I don't have
to do anything since they are represented in the same way in both UTF-
8 and windows-1251 - is that what you mean? But with the cyrillic
chars (which are not exactly that "strange" - probably some of most
used after latin) there should be some kind of conversion (for
example russian letter "A" is represented in UTF-8 by two bytes D0 90
and by 1 byte C0 in windows-1251) - how will ASP "do it for me" - am
I missing something?
Thanks again for your help.
