I use php jpgraph library, but there i a small problem with charsets. lets assume graph.php generates the image, and i call it from some.php
some.php
...
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
...
<img src="graph.php" />
...
as you see, i set charsets in some.php, but it doesn't show the text of the graph, which is in foreign language.(maybe i must set it in graph.php? but how?)
What is the problem?
Thanks UPDATE
even when i try to enter numerical HTML encoding of the Unicode character from here, it doesn't work for Armenia language:/
The meta tag only applies to the content of the page, not to images displayed within the page (even images generated dynamically by your graph.php script)

16 How can I print unicode characters?
Use &#XXXX; format in your strings where XXXX is the decimal value for the unicode character. You may find a list of Unicode characters and there encodings at www.unicode.org Please observe that the encoding in the lists are given in hexadecimal and these values must be converted to decimal.
Note: If You are working in an UTF-8 environment then the characters may be input directly.
