Re: vim seems to have problems rendering this utf8 sequ ence : හොඳ විනෝදයක්

I have to *confirm* my similar experience, that some characters seem to 
be using a width which is a multiple greater (and sometimes smaller) 
than 1 (unity), and that for those characters (specified via Unicode 
reference), there is overlap.

Without knowing the guts of *GVim*, or *MATE terminal* (my environment), 
it seems that the System-default (or Application-default) font for each 
of those is applied universally, and *NOT on an individual character 
basis*.  I assume that that is because of programmer assumptions that 
people would NOT use *mixed-width characters*, and so impose a single 
character width on the entire content display.  Obviously, that is an 
incorrect assumption, because you never know what width the Creators of 
various fonts might use, and the rendering engine should, in my 
estimation, be smart enough to recognize character-by-character width 
(a.k.a. old poured-lead typography plates) and apply those correctly 
where those are used.

And then again, being a text editor which could conceivably by 
definition not concern itself with variable width characters, if GVim 
had a "mode" selector that would permit the setting of display rendering 
to one of the two modes

- universal fixed-width, or

- typesetting variable-width,

then Gvim could offer the best of both worlds. 🙂

Just my own two cents worth!
