Red Hat Bugzilla – Bug 861003
Liberation Mono is not being recognized as a monospaced font
Last modified: 2012-10-05 01:01:03 EDT
Description of problem:
The Liberation Mono font is not being recognized as a monospaced font under various Windows applications, such as HippoEdit.
How reproducible: Always.
Steps to Reproduce:
1. Open HippoEdit
2. Go to Tools/Options
3. Navigate to Syntax Settings/Basic/Fonts And Colors
4. Be sure that "Show only monospaced fonts" is checked.
Liberation Mono is not shown in the list.
Liberation Mono is shown in the drop down box.
* Using Windows 7 SP1 x86_64
* Using HippoEdit 1.50.776 for Win 64 bit
* Manually removed all old Liberation*.ttf from Windows\Fonts and rebooted prior to installation of version 2.00.0.
I can reproduce it. searching for root cause behind this. This is problem of conversion from ttf to .sfd
I discussed this on fontforge users list and found reason behind this is LiberationMono has many 0 width characters other than Fixed width 1229.
Presently fontforge does not set isFixedPitch bit if any character has other than decided fixed width. Some applications use this bit to decide font is monospace or not.
Hoping to find any alternative to fix this bit or may be fontforge upstream will fix this bug.

As inconvenient as this is, it is not a bug in FontForge. As I've just posted on the FF users' list, DejaVu Sans Mono handles this in a way that keeps everyone happy. If only the technique was better documented somewhere!
FWIW, I had the problem with some earlier version (I think it was 1.07), being fixed in a minor release (must have been 1.07.1) afterwards - maybe "accidentally".
Anyway, that release (1.07.1) of Liberation Mono was correctly recognized as a monospaced font.

Yeah, its clear. This is not issue with Fontforge but issue with Proprietary font editors not following standards.
I will fix this issues using fontTools. In long term will do necessary changes to make it true Monospace font.
liberation-fonts-2.00.1-1.fc18 has been submitted as an update for Fedora 18.
* should fix your issue,
* was pushed to the Fedora 18 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing liberation-fonts-2.00.1-1.fc18'
as soon as you are able to.
Please go to the following url:
then log in and leave karma (feedback).
Release 2.00.1 from this site https://fedorahosted.org/liberation-fonts/ fixes the issue for me.
HippoEdit is able to recognize Liberation Mono as a monospaced font. So is Directory Opus (it allows only monospaced fonts to be used in hex viewer).
thanks for confirmation, closing bug
