I'm starting this thread at the suggestion of Nick Shinn, whose participation in the discussion I anticipate. I made the comment here that many typefaces don't support the Romanian language entirely (or rather correctly), by using improper diacritic marks for characters such as ş (and ă and ţ).
The most common mistake in found in ş. It uses a cedilla instead of a "coma" underneath it (just like a ţ).
Here is an excellent discussion on the topic, WITH EXAMPLES.
Since many of the people that participate in these forums are type designers, I just want to signal this problem. Maybe things will be better in the (not so distant) future.
I'm no expert on the subject. Just an occasionally frustrated user.
