Font Chooser
Contents
Common font chooser - a generic dialog when picking a font in applications.
Designers
Objectives
- Specific style. Allow the user to pick a font to be used in an application.
- Generic Family. Allow to pick a family to be used, with some properties of the font to be left to the application/context (weight, slant etc).
- Specialized fonts. Eg: a monospace font
Undecided
- Fine grained control over all aspects of a variable font? That space might be filled with specific design apps. Theoretically a variable font can expose specific attributes such as length of ascenders.
- Personalized. Type choice is very personal, people tend to stick to particular choices. Provide means to curate their personal selection?
Use Cases
- Select a font for a document style, such as headline.
- Pick a font in a limited context (only monospaced for terminal).
Non Cases
- Emoji font selector. Picking an emoji font is the equivalent of widget theme selection. While Tweaks, where I see this being used, might need an emoji font filter, the picking and previewing might need a specific layout.

Constraints
- Various font technologies allow different subsets of features. Variable weight/slant only available in a fraction of fonts available.
Custom tags/axis is available for some fonts. The default tags are width, weight, optical size, italic, slant.
Discussion
I've spent some time prototyping this in the wip/matthiasc/font-variations branch of gtk: https://cloud.gnome.org/index.php/s/cd6Kv5DFGXm42iT
- A related topic would be to provide a dialog for tweaking font settings for a range of selected text in a document or text view
