            Bug ID: 107383
           Summary: Characters overlap when not supported by fallback font
           Product: LibreOffice
           Version: 5.3.2.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: hiunnhue108 at ymail.com

Description:
It seems like that LibreOffice picks fallback font based on the first
character. When the chosen fallback font dose not support the following
characters, they'll overlap each other.


Steps to Reproduce:
 1. Uninstall all Chinese fonts and keep Japanese or Korean fonts as the
fallback fonts.

 2. Open Writer, input some common Han characters, for example "天地人" (sky,
earth, human), which should be supported by most Japanese fonts or some Korean
fonts.

 3. Insert an unsupported character between 天 and 地, for example Bopomofo "ㄅ".

 4. Apply any font which does not support Han characters (Arial or Liberation
Sans for example), so the fallback font will be used instead.

 5. In my case, the fallback font is NanumGothic, which supports "天地人" but not
"ㄅ".

Actual Results:  
Please see attached PDF or PNG.

Expected Results:
Characters should not overlap.


Reproducible: Always

User Profile Reset: No
