*** Consider changing the default display of Variation Selectors
Emacs by default displays the Variation Selector (VS) codepoints not
-composed with base characters as thin 1-pixel space glyphs. The
-Unicode FAQ says that if variation sequences cannot be supported, the
-VS characters should not be shown, leaving just the base character of
-the sequence visible. This could be handled via
-glyphless-char-display, by changing the entries for VS codepoints to
-'zero-width'.
