custom contact form issues

just to let you know, there are 2 issues i have found.

1. custom form validation does not validate as it should… only required/not required check seems to be in place.

2. using russian alphabet as field labels results a function in custom-form.php ($fieldName = preg_replace(‘~[^a-z0-9]~i’,”,$field[‘name’]);) replacing the russian letters, and then user info is saved incorrectly.
