how can iconv charset utf-8 code 737 dont know symbol 'utf-8'

code page 737 = > link

edit

$txt = mb_convert_encoding($txt,'cp737');  

this doesnt work....does not recognize it!

1)so found solution hope helps someone.first of found function of php , other languages has "iconv" known!

2)second must find coding need net.name of coding need windows

3)finally here code need make encoding different before return must convert txt file

$txt = iconv("utf-8","cp737","$txt"); 

so means utf-8 cp737 , thirst parameter txt file created !
