Status: RESOLVED DUPLICATE of bug 1542644

(Core :: Layout: Text and Fonts, defect)

Description

[wujastyk]

Attachment: Screenshot from 2019-05-10 14-37-56.png

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:66.0) Gecko/20100101 Firefox/66.0

Steps to reproduce:

Open WhatsApp web (and several other websites).
View the screen or type the digit "9".

Actual results:

The digit "9" is displayed as a long dash (M-rule).

Expected results:

I expect to see "9"

I'm using Firefox 66.0.5 (64 bit) on Linux Mint 19.1.

The problem goes away if I untick the preference "Allow pages to use their own fonts..." That's a reasonable kluge, but there are many pages where I need the page to use its own fonts, e.g., when PDFs are displayed.

Comment 1

[Jonathan Kew [:jfkthame]]

Do you by any chance have a Lucida Grande font installed? I think this is a bug in a specific (old) version of Lucida Grande; see bug 1542644.

Comment 2

[wujastyk]

Yes, I had Lucida Grande installed (but not selected in the Firefox font options). I deleted the font files and the problem appears to have gone away. Magic. A flawed mort table - who'd have guessed.

Thank you, Jonathan! I never would have thought of that in a thousand years.

Best wishes,
Dominik
