Description Kenneth Hanson 2020-03-31 20:50:39 UTC
Description:
Under Character Formatting > Font Effects, one can choose "character emphasis" from among the following: dot, circle, disk, and accent.

These appear to be low resolution bitmaps, which are inappropriate for 2020. Additionally, the accent mark has a jagged, misformed shape.

Furthermore, they render with many glitches in LO. Shapes change as you zoom in and out, such the the "disk" sometimes looks like a teardrop. Sometimes there are gaps in what should be solid lines. Altogether, they look terrible at most any zoom level. In principle this may be a separate issue, but I suspect that whatever is done to replace these with vector graphics or symbols from a font would also fix the rendering problems.

These marks are not rendered correctly in print and PDF export, reported separately as bug 131751. Summary: only one mark is produced for an entire formatted character sequence.

Yes if possible, these should probably be replaced with Unicode combining diacritics.

Comment 7 V Stuart Foote 2025-06-01 23:37:05 UTC
Can the Char dialog Emphasis marks (Dot, Circle, Disc, Accent) be handled the same as the Ruby annotations, as SwMultiPor? The Ruby seems to offer better font rendering than the current char emphasis marks that seem bitmaps.
