Using annotations in matlab I noticed that when I use colored text the spacing between words increases. See the example below
Is this a know bug? Can it be fixed with some workaround?
annotation('textbox',[.2 .5 0 0],'String',["a a a a a a a a a a" "a a a a a a a a a a"],'FitBoxToText','on','FontName','consolas','FontSize',14)
annotation('textbox',[.2 .5 0 0],'String',["a a a a a a a a a a" "\color{red}a \color{black}a \color{red}a \color{black}a \color{red}a \color{black}a \color{red}a \color{black}a \color{red}a \color{black}a"],'FitBoxToText','on','FontName','consolas','FontSize',14)

@dpb what do you mean with renderer? Interpreter? If so, we can only use 'tex'.
The same happens with bold
annotation('textbox',[.2 .5 0 0],'String',["\bfa a a a a a a a a a" "\color{red}a \color{black}a \color{red}a \color{black}a \color{red}a \color{black}a \color{red}a \color{black}a \color{red}a \color{black}a"],'FitBoxToText','on','FontName','consolas','FontSize',14)

I suspect it's all tied in to the font family and the TeX implementation. Probably not much could be done as AFAIK TMW just picked up an opensource TeX distribution and embedded the necessary pieces.
