Don't count zero width space in hasGlyph layout
For sequences that may form ligatures (ie not just a a base
character plus variation selector pair), hasGlyph requests a layout
and then counts the glyph. In some cases, when the source string
contains a variation selector, the layout contains space glyphs with
no associated width, which causes a "false" result. This patch
filters out such zero width spaces.
