over the screen, for all windows comprising one instance of Vim. One narrow
character occupies one cell, one wide character occupies two cells. The cell
size changes when you set the 'guifont'. The GTK2 GUI (alone among all
versions of gvim) will accept a font whose glyphs aren't all the same size,
but it will clip wider glyphs at the cell borders and it will fill narrower
glyphs with empty space, making the result ugly. Other gvim versions require
monospace fonts (which may be TrueType or OpenType); I have met fonts which
pretended to be monospace but weren't: for instance, the bold Cyrillic glyphs
of the Lucida Console font are one or two pixels wider than the character
cell. The result, again, was ugly.

FZKaiTi for CJK, and it doesn't give me problems. (On Windows my favourite CJK
font used to be MingLiU and my favourite Latin font, Lucida Console.)
