           Summary: Unicode BiDi characters break font rendering
           Product: LibreOffice
           Version: 5.4.0.0.beta1
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal

          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
If text inserted Unicode BiDi characters, they could be rendering with fallback
fonts.

Steps to Reproduce:
1. Copying some texts from
https://en.wikipedia.org/wiki/Bi-directional_text#Chinese_characters_and_other_CJK_scripts
2. Paste into Writer
3. Set CJK font face

Actual Results:  
When CJK texts surrounding by BiDi characters, they aren’t rendered with
specified font, using fallback fonts instead.

Expected Results:
Text surrounding with Bidi characters should be rendering with specified font
even if the font does not has corresponding grapheme.
