Multi generated files encoding problem

[mraiur]

Hi .

  i need to generate multiple *.xml files and the problem is that when i generate only the fist file gets the php header from the generation script .

example:

1-file: utf-8

2-file: ASCII

3-file: ASCII

 

and can someone tell me how can i set a encoding foreach generated file

* but i cant put <?xml encoding="" ?> becouse the script is a cache script;
