OK! I always use meta tag <meta http-equiv="content-type" content="text/html; charset=windows-1251">, but it is not working in UBB 6.0 beta7.* <img src="https://www.ubbcentral.com/boards/images/graemlins/frown.gif" alt="" />

I'm experiencing the problem, which is the usage of ISO charset by UBB6 pages. It doesn't care for any meta charset codes, and the only way to set your own encoding is manual.
I'm using following meta tag on my UBB6 (beta 7.9), which works just perfectly on UBB5 (5.47d):
<meta http-equiv="content-type" content="text/html; charset=windows-1251">
Please look into the problem. If it already been solved, please point out what's needed to be done to use custom charsets.
