I had tried these characters just at simple html page with nothing else, then it works fine but as i am going at my actual site it convert all the text in question marks, i do not understand why its doing this.
"Most Russian-language Web pages (more than 90% for sure) are made nowadays in Windows-1251 encoding a.k.a. "Cyrillic(Windows)", just because the majority of authors work under MS Windows nowadays and 1251 is what Microsoft uses for Cyrillic, so built-in Windows Cyrillic fonts and keyboard tools are for Windows-1251 encoding."
I have read all these kind of stuff. and it works fine if i use plain html page with just text. But when i use .php file and including different files in main file and my data is coming from database then it all goes wrong. :(
Thanks for the help. But now i had resolved the issue by using hexadecimal codes. I tired every option but that was not working accurately thats why now i am using hexadecimal characters for russian text.
