Hi Murray,
Alas C6 doesn't really support unicode, so there may be an issue there.
I believe C7 has unicode support.
There may be other ways of doing Cyrillic though. There are plenty clarion programmers in Russia, which seems to imply there are many possibilities. I'm guessing the place to start is to set the pages (via CSS) to use a font that supports Cyrillic.
You can also change the HTML Charset that the server uses by setting it in
the p_web.site.HtmlCharset property.
To change it on a site-wide basis set this property in the WebHandler, in the ProcessRequest method, before the parent call.
For Cyrillic you could try setting it to
ISO-8859-5
Cheers
Bruce
