Hmm.  We can only help you if you identify the problematic font.

No TeX font has a space *glyph* within its fonts.  In TeX, the word
space is always stretchable and shrinkable, and TeX doesn't have the
concept of inter-letter spacing, thus a space glyph (with a given
width) is completely unusable.
