System Information
Mac OS X 10.10

Blender Version
Broken: 2.74

Short description of error
TTC files contain multiple TrueType font styles in one file (regular, bold, italic, etc.), but Blender only seems to have access to one

Exact steps for others to reproduce the error
In any Blender scene:

Create a text object.
Assign it a font from a TTC file. You can use GillSans.ttc as a sample font file; this file contains regular, italic, bold, bold italic, and several other styles (9 total, as verified by the Font Book utility).
Notice that regardless of which of Blender's slots the font is assigned to, and regardless of the settings of the Bold and Italic buttons, Blender only ever renders the font in regular style. There appears to be no way to get to the other styles in the file.

Blender doesn't support ttc container format.
Support could be added but this is not some mistake or error in Blender's code.

closing.

It supports it well enough to recognize the file type in the font dialog, and to get one font out of a TTC file. So perhaps the bug is actually that it let me open a TTC file in the first place. If that's so, then I'll file a new bug report for that, as well as a feature request for TTC support. Does that seem reasonable?

@marnen. We don't limit what freetype can open (it has support for a range of formats), but I don't see it as being that useful to explicitly disable TTC either.

It definitely seems like a bug from a user's point of view if you let me load a ttc file but then fail silently when trying to use it. If the italic font in the ttc can't be used, it should not permit the ttc font to be used in the 'italic' slot? (Similarly for bold etc.)

As a workaround, here's an online thingy that lets you extract .ttf files from a .ttc file:
https://transfonter.org/ttc-unpack

But I agree with the OP, having this supported in Blender would have saved me 30 minutes of research today.

This is still an issue - why are devs closing issues like this willy-nilly? Yes, the workaround is doable but it took some time to find when this could simply work as expected. 😡

UI: disable TTC fonts in the file selector #121060

Looking into the issue again, not showing TTC files in the file selector (without explicitly disallowing them) seems like it may best so users don't run into broken TTC support. Submitted !121060.

UI: disable TTC & OTC fonts in the file selector

I would like to see the “Disable TTC & OTC” change restored.
It is too much of a disadvantage for users to no longer be able to select TTC & OTC.
And it takes a lot of effort to research and deal with this sudden and capricious change.

@FA as these aren't supported, showing them as supported makes users spend time to attempt to use the fonts which they can't properly access.

The proper fix in this case would be to add support for selecting the font styles within these formats.

I don't use blender much at the moment, but I still get mails about this issue. To me the latest change seems like a mistake. The issue can be summarised as

TTC files are supported but only partially, and
the user interface does not make it obvious that the support is only partial.

Given this, it seems kind of obvious that there are two possible ways to fix the issue:

option 1: add full support for TTC files
option 2: make it obvious that support for TTC files is only partial.

What definitely isn't a fix is removing TTC support entirely. That is just a regression and it doesn't help anyone.
