English is not the native language for the system i'm working on, so i had to use some techniques to get it working. There's only thing i cannot understand:

In my .js file there's a ColumnModel description where in header i use Russian letters:

PHP Code:
ScheduleColumnModel = new Ext.grid.ColumnModel(
And that header is shown in weird symbols! What is the matter?

Thank you!!

The .js-file is in UTF-8 format.
The data from database is provided in UTF (i put mysql_query("SET NAMES UTF8") before the query).
