The out commented code is confusing in TTFontReader>>decodeCmapFmtTable:

Hi,
First of all thank you for the new version of Squeak. It's really great.

Special thanks for Tobias and Marcel for the font import tool! It works perfectly.

Nevertheless I have noticed that there is a regression in Squeak 4.6/5.0 in the font handling. It's not possible anymore to use non-english characters even after loading a font that contains them (I've changed the code font and tried to use the characters in a workspace).
Unnamed1.1.cs
Can anyone verify?
