Screenshot of the cent glyph as displayed in OpenOffice.

Description of problem:
The character 'cent' (¢) has been modified in Liberation Mono and Liberation
Sans without regenerating hints, as has already been discussed in bug 474522.

Version-Release number of selected component (if applicable):
1.06.0.20100721

How reproducible:
Consistently, as long as bytecode hinting has been turned on.

Steps to Reproduce:
1. Use a version of Freetype with bytecode hinting enabled.
2. Make sure that hinting is set to 'full' in your window manager's
appearance
preferences.
3. Enter the character ¢ (U+00A2) in an application such as OpenOffice.
4. Set the font to Liberation Sans Italic or Liberation Mono Italic.

Actual results:
The cent sign looks correct.

Expected results:
The cent sign is warped beyond recognition.

I've been playing around with the font, and it's actually even more complicated
than it seemed at first. It's not merely a matter of regenerating instructions;
that has, in fact, been done. The problem is that FontForge's auto-instructions
conflict with the global instructions which were manually coded by Ascender;
the glyph looks slightly better removing instructions entirely.

Would it be better to revert to the 1.03 version of the cent glyph (no
cross-bar)? Or just leave the glyph unhinted?

The other alternative, of course, is to find a contributor who actually has
knowledge of bytecode hinting. I'd fix it myself, except I don't know the
slightest thing about TrueType hinting myself.

Anyone here have any knowledge of TrueType instructions who might be able to
fix this? (DejaVu contributors, perhaps?)
