Summary: Hinting on 'cent' glyph in italic fonts broken
https://bugzilla.redhat.com/show_bug.cgi?id=620606
Summary: Hinting on 'cent' glyph in italic fonts broken Product: Fedora Version: rawhide Platform: All OS/Version: Linux Status: NEW Severity: medium Priority: low Component: liberation-fonts AssignedTo: psatpute@redhat.com ReportedBy: cody@zone38.net QAContact: extras-qa@fedoraproject.org CC: petersen@redhat.com, fonts-bugs@lists.fedoraproject.org, psatpute@redhat.com, i18n-bugs@lists.fedoraproject.org Classification: Fedora
Created an attachment (id=436160) --> (https://bugzilla.redhat.com/attachment.cgi?id=436160) 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.

--- Comment #1 from Cody Boisclair cody@zone38.net 2010-08-02 21:30:28 EDT --- 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?

--- Comment #2 from Cody Boisclair cody@zone38.net 2010-08-02 21:36:08 EDT --- 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?)
