The correct bold and italic occur on the right, in HTML view. The correct bold and italic also apply for all other text editors.

I am currently filing a bug regarding improper bolding and italicizing of Unifont, a monospace font that supports almost all of Unicode.

I am a Linux user who has Unifont installed. Unifont has bold and italic glyphs stored under the same file as the base glyph.

On Libreoffice, whenever I bold or italicize Unifont on Libreoffice only, Libreoffice creates "faux bold" and "faux italic" transformations where I find it highly undesirable.

This applies to all installs of Unifont. I am a Linux Ubuntu user.

One should also note that the normal, bold, italic, and bolditalic forms of Unifont are bundled into one ttf or otf file.

Other fonts have separate TTF or OTF files for the respective four forms.

Italics and bold work for century gothic "GOTHIC" but not for Unifont on Libreoffice. This applies for all libreoffice apps.

I don't understand, why html view is correct one. I don't see a difference. Please describe the actual and the expected result and paste informations from Help -> About Libreoffice. thank you

The faux bolding and italicization on Libreoffice is more intense, more characteristic of the faux bolding and italicization of typefaces without bolding and italicization. The one on the right is more analogous to "arial bold" and "arial italics", in which Arial do have bold and italics version, but the italics is a professionally designed oblique form.

Thanks for you expanation, but I can't assess this. Perhaps somebody else can confirm the problem.

I'm not a font expert, but I'd say this is a duplicate of bug 103596.
Comment 8 ⁨خالد حسني⁩ 2022-09-21 18:49:03 UTC
Unifont comes only in a regular style, whatever you are seeing in other applications are also synthetic (faux) styles. There is no standard that defines how much to slant or embolden a font, so different applications might give different results.
