[i18n] Converting the Czech translation from ISO 8859-2 to UTF-8

Sorry, my mistake, the problem does not lie in the input encoding, but 
in the output encoding. Let me give you an example from the czech nag.po 
file:

msgid "_List Tasks"
msgstr "_Seznam úkolů"

This works correctly, the letter S gets underlined in Horde and works as 
an access key, ALT+S. The problem occurs, if you try to do something 
like this:

msgid "_List Tasks"
msgstr "Seznam _úkolů"

Horde displays this string AS IS, "Seznam _úkolů", instead of 
underlining the letter ú. And the shortcut ALT+U does not work. This 
means that characters with diacritical marks cannot be used as access keys.

(I am aware that this is not the best example, because in this 
particular case letter S gives more sense as an access key.)

File /horde/config/nls.php contains this code snippet:

'charsets' => array(
...
'cs_CZ' => 'ISO-8859-2',
...),

If you changed it to

'cs_CZ' => 'UTF-8',

then the PO file could contain this:

msgid "_List Tasks"
msgstr "Seznam _uúkolů"

Horde would render the string as "Seznam úkolů (U)" and ALT+U would work 
as access key.
