#112 Glyph ID mismatch when using Type 1 font as system font

[Arthur Reutenauer]

See this question on TeX StackExchange and that thread on the TeX Live list.

XeTeX, when using a Type 1 font via fontconfig, seems to pick up the wrong glyph IDs at times. I’m even observing wrong metrics as well, probably due to XeTeX / xdvipdfmx picking up an incorrect unit per em value. See attachments.
