We use Usermin in Czech language to set autoreply (vacation) e-mails. Right now the autoreply.txt file saves in ISO-8859-2 encoding (BTW: why not Unicode?), but the autoreply e-mail that is sent has garbled diacritics (letters like ěščřžýáí) - perhaps the encoding is not defined in its header, or is defined wrong?
I tried to solve this by editing the /etc/usermin/forward/autoreply.pl file, i changed line 243 to this (I guess there was a variable with encoding autodetection result in it):
$type .= "; charset=".($cs || "iso-8859-2");
But - didn't help, which shows I'm really not a programmer:) now it displays fine in GMail, but that's it, roundcube, squirrel, outlook - all wrong.
I hope we can solve this problem. Thank you for developing webmin and usermin, great pieces of software!
The best fix is to either use the field on the autoreply form to enter the correct character set, or at the top of the autoreply text add the line :
Charset: iso-8859-2
The next Usermin release will make this more automatic ..
