Error on file saving

When I create file on Windows hosting, it gets name like джулия.jpg

It has to be a cyrillic name.

fopen() is used开发者_开发百科 for creation.

What can I do with this?

It's an encoding issue. Setting PHP to use UTF-8 encoding will probably suffice: http://php.net/manual/en/function.utf8-encode.php

UTF-8 can represent every character in the Unicode character set, plus it has the special property of being backwards-compatible with ASCII.

• Check if all the script files use the same encoding (ANSI, ISO-..., UTF-8, etc).
• Check the internal encoding your script use and the encoding of the string
  • multibyte functions
  • internal encoding of your script
  • encoding of your string
• NB: Not recommending you to use string input from websites in the filesystem!
  • But if you expect input in a certain format, be sure to specify the content type of your html page.
