            Bug ID: 137738
           Summary: The width of a " " (U+00A0, NON-BREAKING SPACE)
                    changes when italicized
           Product: LibreOffice
           Version: 6.4.6.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: trivial
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: zegolem1383 at outlook.fr

Description:
If I write a " " (U+00A0, NON-BREAKING SPACE) in LibreOffice Writer, select it,
and make it Italic, it will get slightly wider. The behavior isn't replicated
for a normal space, and seems to be a bug, as when this same character is also
underlined, the underline stays the width of the non-italic character, causing
it to be slightly shorter.
This is actually mostly noticeable when underlined italic text contains this
character, as it breaks the underline in a fairly noticeable way.

Steps to Reproduce:
1.Type a U+00A0 in Writer
2.Select the U+00A0 character
3.Click the "italicize" button, or press Ctrl+I
4.Observe the width of the selection (and therefore, the width of the
character)

Actual Results:
The width of the selection (and therefore, the width of the character)
increases.

Expected Results:
The width of the selection (and therefore, the width of the character) should
stay the same, as this is the behavior of a normal space (U+0020).


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
Version : 6.4.6.2
Build ID : 6.4.6-2
Threads CPU : 4; OS : Linux 5.8; UI Render : GL; VCL: kf5; 
Locale : fr-FR (fr_FR.UTF-8); Langue IHM : fr-FR
Calc: threaded

(running KDE Plasma on Manjaro Linux, was also reproducable with OpenGL
disabled)

This was marked as a Writer bug because I couldn't reproduce the issue in Draw
or Calc.
