I face this bug on LibreOffice Writer 188.8.131.52 On Ubuntu 14.04!

Shows space between letter and another related problem!
I think the extra white space problem that occurs some times between some Arabic/Persian fonts character is related to another problem that is mentioned as "extra-dash" in the picture!
Looks similar to the kashida problems found in other bug report so adding them to see also.
Looks like you don’t have a bold version of this font (AFAIK Arabic Typesetting has only a regular font), so what you are seeing is the effect of fake bold done by FreeType. Can be easily verified by trying to make bold text using this font on onther application.
Tried to make it bold in Calligra Words but it wouldnt allow me to do so and Calligra only listed regular and italics for that font.

*** Bug 97329 has been marked as a duplicate of this bug. ***
This is simply a bug in how FT_GlyphSlot_Embolden() works (the FreeType function we use to create synthetic bold) as it increases the glyph width which causing such bugs.
This should be fixed with bug 89870, as we now always use original glyph metrics not FreeType one (that this function changes).

with and without harfbuzz
Find the extra spacing between characters in the non-harfbuzz engine better than then harfbuzz version.
