Bug ID: 161389
Summary: [META] Font fallback-list issues
Product: LibreOffice
Version: Inherited From OOo
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
The ODF format supports [1] setting more than just a single font, but rather
setting a list of fallback fonts so that if an item on the list is not
available with the appropriate features on the system (e.g. no such family at
such size), then the next list item - the next font - is chosen. This is
intended to make font choices more robust for display on systems which don't
have the same installed fonts as the author's.
This feature is similar to how font selection is defined in SVG files and in
HTML files via CSS; see:
https://css-tricks.com/css-basics-fallback-font-stacks-robust-web-typography/
This bug is intended to track the various internal logic and UI issues stemming
from the use of these lists and the need to support it in LibreOffice.
NOTE: This is _not_ the same mechanism as global font substitution (bug
103342), though they are related.
