Bug ID: 155203
Summary: Formatting: LibreOffice Writer can't access the
superscript OpenType feature on certain fonts
Product: LibreOffice
Version: 7.5.3.2 release
Hardware: All
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
LibreOffice doesn't access the superscript OpenType feature ("sups") as it did
before on certain fonts. This makes the footnotes and endnotes not
well-formatted, if you use the superscript feature instead of the superscript
emulation.
Steps to Reproduce:
1. On Windows 11, install the Merriweather Sans typeface family
(https://www.fontsquirrel.com/fonts/merriweather-sans);
2. Open the attached sample document (it was already formatted to show the bug,
with the superscript *emulation* disabled);
3. Verify that the footnotes' characters are not superscript, even if the
"Footnote anchor" text style is correctly set ("Merriweather Sans Light:sups");
4. However, press F11, find and edit the "Footnote anchor" text style to use
"Calibri", and select the superscript feature (alternatively, just type
"Calibri:sups" without quotes on the typeface name field). LibreOffice
correctly uses the superscript feature of the Calibri font, while it doesn't
use the Merriweather Sans superscript feature.
Actual Results:
LibreOffice doesn't use the superscript feature built into some fonts.
Expected Results:
LibreOffice should use the superscript feature built into every font.
Reproducible: Always
User Profile Reset: Yes
Additional Info:
The superscript ("sups") OpenType feature is not the same as the LibreOffice
emulated superscript:
The superscript *feature* is located at <press F11>, go to Character style, go
to a text style ("Footnote anchor", for example), modify the text style, go to
Font tab, activate the Features button, select the superscript option and
verify if the superscript *emulation* is disabled so to not have any conflict.
The superscript *emulation* is located at the Position tab (instead of the Font
tab), and does not gives the optimized superscript glyphs made by the font
designer.
