Tilman Hausherr resolved PDFBOX-5920.
-------------------------------------
Resolution: Fixed
There's now a snapshot at
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/3.0.4-SNAPSHOT/
I looked at the other files... Sadly, these are files where the fonts itself
return bad data. I won't change the code parts that retrieve width for code 32
this time despite that I don't trust this, because all alternatives I tried
also brought some quality loss in some files. Maybe the text extraction
algorithm itself should be improved.

> WinAnsiEncoding supports not all available characters from the font. That is
> the reason why we moved to the workaround proposed by FAQ, also to use
> PDType0Font. Now we have realized, that returned space width from
> font.getSpaceWidth() returns invalid value.
