Free TrueType font for CAD projects

What is osifont

In some European countries, CAD projects must have font which conform to IS0 3O98 specification. Commercial CADs has this font, but free CADs not. There is no available free font yet, so this project will fix this. This font will be created completely from the scratch. Font is created with free tools like FontForge, Inkscape, Gimp. Font is available under 3 licences: GNU GPL licence version 3 with GPL font exception, GNU GPL licence version 2 with GPL font exception, GNU LGPL licence version 3 with GPL font exception.

osifont's Issues

List of Linux packages installing the font

could you provide a list in the readme which package in a Linux distribution installs the osifont, if there are any packages already? Thank you.

Create a release

Hi !

Awesome work on the fonts !

Can you make a "release" on github to ease the download for the non "github-aware" people interested on this work ?

Thanks !

Issue with spacing in Qt and Small sizes

I have posted this problem in the Qt forum but there they say it is moslikly a problem with the font and not with Qt so here I am. Whenn I create text with Qt that is smaler than 2.4mm I get weard spacing betwen some of the chareaters.

Italic style map

The osifont-italic.ttf style map is set to regular instead of italic when generated in FontForge. This causes issues when trying to use both italic and regular font styles (for example in CAD programs).

Issues with Cyrillic

1. «з» is too tall, it shouldn’t be taller than any other lower case letter
2. «в» has the bottom part smaller than the top part, should be other way round
3. «ь» is not the same as «b», and should basically look the same as the left part of «ы»
4. «и»/«й» is too wide, should be the same width as «н»
5. «У»/«Ў» is too narrow, should be at least as wide as «П»

Also, one of the languages is named incorrectly, it’s Belarusian, not Belorussian.

Monospace even thought it is set to Modern(Variable width)

I discovered that the newest version of the font is monospace even thought it is set to Modern(variable width).
This problem is a bit more discussed in the FreeCAD forum.
I tested it with a Linux(OpenSuse 15.3) and a Windows 10 PC and get the same results, I also tried changing the Element->Font Info->OS/2->Panose->Proportion Value to something different but this didn't change anything.

generate.sh

but how is osifont-italic.ttf generated? never mind not too hard, but a Makefile instead of generate.sh would be nicer anyways...

How does the license affect programs that embed this font?

The OFL SIL license allows a font to be embedded in a computer program, without any requirement on the license of the program (ie: the copyleft doesn't affect the program). How does the license of osifont behave regarding this? (you explicitly mention in the readme that one use case of the font is in CAD programs, so I guess this question is an important one).

LICENSE missing

the license files are missing in the repository

GPL and LGPL licenses are too complex

The GPL and LGPL licenses are very hard to decipher exactly how they apply.

Can you please in your README give us a clear explanation on:

• How this font can be used in OpenSource projects
• How this font can be used in ClosedSource Commercial products
• Is the font legally eligible for web embedding?

Out of curiosity, was Is there a reason you didn't want to publish this font project under the MIT license?

Barred 7?

I don't have a copy of ISO3098 handy, but I'm pretty sure the 7 should be barred.

Please add a glyph

Hi,
The glyph for unicode U+2B21 WHITE HEXAGON could be useful.
See also WHITE SQUARE (U+25A1).

Vertical font alignment?

I have the issue that the font is not vertically aligned correctly. Or is this a feature of the font philosophy? So, when using Gnuplot or LibreOffice, the font always seems to be have its vertical center anker at the very top (see image below).

Anyone has an idea to solve this?

Sizing does not work

Hi,
There is a sizing problem with version 0.1.20150506 of this font. In the software Creo Parametric (x-server xtop.exe) sizing does not work at all, the font is always displayed at approximately 42 points height.

Using "dp4 Font Viewer v3.3" the issue could be indicated by the placement of the glyphs(?) in the comparison view - notice the grey font separator line (not a graphics problem, see attached screenshot).

"Microsoft Font Validator 1.0.1286.23890" shows 150 "Bounding box is incorrect" errors, as well as 2 other errors which might not be related to the sizing issue (see attached report).

kerning for "P.D"

Description

Kerning rules for strings starting in P. or P, may cause intersections of P with subsequent glyphs.

Environment

Debian 10 LibreOffice 6.1.5.2
Debian 10 Inkscape 0.92

Expected Behavior

A string such as P.D should be wider than the string PD.

Actual Behavior

The . glyph causes the entire string to be narrower.

Steps to reproduce

1. Install osifont.ttf (e.g. Download osifont.ttf into ~/.local/fonts/. Set permissions to 644 using chmod 644 ~/.local/fonts/osifont.ttf as directed by Debian font install docs. Run fc-cache to make font available to applications (e.g. LibreOffice)).
2. Start up LibreOffice
3. Set font dropdown menu to osifont.
4. Type PD
5. Type P.D

Demonstration of bug

• LibreOffice example screenshot
• Inkscape example showing various other problematic combinations

it's not just russia that's using cyrillic?

so mind undoing the removal?

Font position too high?

Hello,

I'm looking for a good font for technical drawings and love this font. However, when testing I noticed that the vertical alignment of the glyphs is very high compared to other fonts (see image).

This causes issues in tables where the upper area of the glyphs touches the table borders. The vertical alignment doesn't look centred and seems off? Is this deliberate by design or an issue to be improved?

Kind regards,

Wouter
