            Bug ID: 121256
           Summary: [ENHANCEMENT] Display directionality formatting marks
           Product: LibreOffice
           Version: 6.0.5.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: page74010-sf at yahoo.fr

Description:
When working in CTL environment, there is sometimes a need to insert a
"foreign" word or acronym made of mixed-category characters (Latin letter +
symbols within an RTL flow or RTL chars + symbols in LTR flow), like C++. When
the "word" can clearly be classified as LTR (or RTL) there is no difficulty.
However, if the symbols, which are direction-neutral, lie on the edges of the
sequence, their directionality property will be interpreted in the "main text"
context, resulting in splitting the "word" into the LTR group +
symbols/punctuation concatenated in the "main text". This results in the
acronym, like C++, being displayed as ++C.

The workaround is to enclose the sequence between U+200E LEFT-TO-RIGHT MARK and
 U+202C POP DIRECTIONAL FORMATTING.

However, there is presently no visual feedback that such marks have been
inserted in the text, which makes editing the insert difficult: one needs to
erase more than the insert to make sure the marks have been deleted et retype
the extra deletion.

The present enhancement requests that the bi-di marks be displayed like "soft
hyphen" is (at least when View>Formatting Marks or View>Field Shadings is
enabled).

Actual Results:
Presently, no visual clue about directional marks presence

Expected Results:
Wishing a visual feedback about directional marks presence


Reproducible: Always


User Profile Reset: No
