Description hammerquill 2023-09-11 10:25:48 UTC
Description:
7.5 and 7.6 both do this: In Writer, opened a .doc, changed the font from Times New Roman to Adobe Caslon Pro. There are paragraphs that are in bold italic, but somehow LibreOffice has Bold checked, but not Italic - presumably to do with Word formatting. (I don't have Word to check what's going on in the original.) In this context, the digraphs Th and ff render as a random shape of scattered dots. If you reformat the passage within Writer in any way, it renders correctly, so it is not a big problem, but it indicates that there is something odd going on when converting files from .doc, and/or something wrong with rendering certain fonts.

Steps to Reproduce:
1.Some sort of formatting in Word yields Bold Italic, though LibreOffice's toolbar only shows Bold selected. The text rendered is wider than normal Bold Italic.
2.Format the text in Adobe Caslon Pro
3.Include in the text Th or ff. 
4.Do not reformat to Italic using Writer.

Actual Results:
Th comes out as a messy block of dots. ff comes out as a blank space with a couple of dots high up.

Expected Results:
Th and ff digraphs should be auto-replaced correctly.


Reproducible: Always


User Profile Reset: No

Additional Info:
I have a screenshot of the Th failure. Unfortunately I don't know in detail what the original document had that rendered as bold italic without LibreOffice seeing it as italic.

Please attach a sample file.
Can you test in safe mode?, Menu/Help/Restart in Safe Mode
Comment 2 hammerquill 2023-09-11 22:22:15 UTC
Tried in safe mode, and it still does the same thing.

Created a document starting from an excerpt of the original document to preserve the unknown formatting. Included digraphs Th, ff, fi, ffl, ffi. fi worked fine, but the others were all garbled to strange alternates. Selecting the text and using the toolbar to change it to italic (though it already looked italic) again fixed all of them.

Should be self-explanatory.

This is how I see it.
But I have not 'Adobe Caslon Pro' installed.
