How do I correct the character encoding of a file?
===
I have an ANSI encoded text file that should not have been encoded as ANSI as there were accented
characters that ANSI does not support. I would rather work with UTF-8.
Can the data be decoded correctly or is it lost in transcoding?
What tools could I use? | 0 | [

php - proc_open
===
I need to do some command lines through a browser.
What I need to do in a command-line would be:
$login
<login name>
<password>
$passwd
<old password>
<new password>
<retype new password>
So, how can I do this using the [proc_open][1] function?
Thanks
