4. Current solution
Not working in the character dialog

5. Information 1/3
● Benjamin wants to get the text as close as possible to
the original (and don’t cares about substitution).
● Eve wants to clearly see if the current selection has
been substituted to understand possible differences
(tdf#61134, tdf#94327).
● Eve wants to understand what fonts are substituted in
the current document to make the decision if installing
makes sense, for example (tdf#78186).

6. Information 2/3

7. Information 3/3

8. Substitution 1/2
● Eve wants to make the current
substitution permanent to use only open
formats in future (tdf#104667)
but restrict to
used only
(tdf#95062).

9. Substitution 2/2
● Eve wants to manage the font
substitution table to learn how fonts are
replaced and to manipulate the
association (tdf#64509, tdf#94327).

10. 2. Font selection

11. Listing 1/3
● Benjamin wants to select one from the
installed fonts without getting bothered
by too many style variations (tdf#35538,
tdf#66792).

12. Listing 2/3
● Benjamin wants to hide fonts that are
disabled in the system (tdf#77878) or not
relevant in the context of LibreOffice
(tdf#88416) in order to have a smaller
fonts list (tdf#91130).

temporarily

13. Listing 3/3
● Benjamin wants to filter the fonts list acc.
all/used/favorite (tdf#101748), highlight
used fonts (tdf#90161) as well as locale
(Chinese for instance) (tdf#114764).

18. Summary
● Improve font substitution (infobar,
substitution table, dropdown, preview)
● Provide means to hide and to highlight
fonts (options dialog, font selection,
dropdown)
● Make fonts extendible (don‘t bundle any
font, enhance extensions and integrate
with system)

19. Some basics about typeface
● Serifs (with/without)
● Height (ascender/descender),
Width (spacing/tracking)
●
Proportional/monospaced
● Weight/thickness (thin, light, bold, heavy…)
● Slope/slant (italic or oblique)
