Fontra does not yet support the concept of sources being "on" or "off", so the rcjk "on" flag currently causes a source to be ignored (good) but the source will be gone once written the glyph gets written back to the backend (bad).

We need a counterpart of googlefonts/fontra#639 in this repo, too.

@fatih-erikli

If a glyph contains classic components as well as variable components, the classic components are lost.

Also, when writing a glyph, we should avoid mixing the two: if there are any variable components present, all components should be written as variable components.

Currently if anything is added to the Note section in RoboFont (in the Inspector panel), Fontra would erase it when saving changes.

In certain situations the username string is saved in double quotes.
This is probably caused by the inclusion of certain characters, such as @. The issue is reproducible on all browsers.

Introduced here:

• 8519cdc

Fixed in django-mysql as part of googlefonts/django-robo-cjk#109

For example:

• guidelines
• lib public.markColor

We should probably always parse the original data first before applying our changes, just like the designspace backend does.

If a new project gets added or if a user is added to a project, they will not see the project until the Fontra server restarts they log out and log in again.

These are designed to work nicely in URLs.

This may be a combination of two things

• The code itself is buggy
• The watchfiles oddity worked around in the ds backend here: googlefonts/fontra@063923f

The watchfiles oddity probably deserves a wrapper, so that watchfiles client code doesn't need to worry about it.

• Check how it works, what glif_list + updated_at gives us in that case
• Fix whatever is broken

This repository is mostly library code, that can be useful outside of the Fontra app. I think we should change the license to Apache.

Relates to googlefonts/fontra#548

fontra-rcjk is really two things:

1. A Fontra plug-in to communicate with a https://github.com/googlefonts/django-robo-cjk server
2. A Fontra plug-in that implements the rcjk file format

These two share a lot of code, but conceptually only the second item is truly library code.

See googlefonts/django-robo-cjk#108

The name limit is 50 chars. Perhaps the django-rcjk backend can mangle long names and map them back.

Fontra doesn't (yet) have neither a status field like .rcjk has, nor a glyph.lib where we could keep it.
