Unable to load certain custom fonts in epub

[phdpe]

Build: 3.7 prerelease, built 24299 on windows 11.

Issue: unable to change to certain custom fonts in epub files. Received "Font not found" error message even though the font was correctly installed to "C:/Windows/Fonts", and can be selected in other programs. It is able to load some common fonts, such as "Arial", but not the ones that I installed in Windows.

Step 1: verify font Literata was installed correctly in C:/Windows/Fonts

Step 2: Font Literata was available in "eBook Settings", and selected.

Step 3: error message "Font Literata not found, using the default font".

SumatraPDF only looks for ebook fonts as files in C:\Windows\Fonts, while the font list in eBook Settings comes from Windows itself. If you installed Literata with a double-click and Install, Windows puts it in your profile (%LOCALAPPDATA%\Microsoft\Windows\Fonts) and the Fonts window still shows it, which is why it appears in the list but can't be loaded. Right-click the font files, choose "Install for all users", then restart SumatraPDF.

Thank you. In case anyone cant install a font for all users, a workaround is to use CustomCSS to add a font-face.

@junkerderprovinz well described so @phdpe
1 here is the epub text

2 here is turn the embedded font off and use default

3) here it is with GLOBAL ALL USERS Literata

Fixed in a8cfb42ad. SumatraPDF now also loads fonts installed only for the current user (%LOCALAPPDATA%\Microsoft\Windows\Fonts), so "Install for all users" is no longer needed. It will be in the next pre-release build.
