Sorry, something went wrong.
... by telling TeX to treat \u2212 (unicode minus) as a minus sign.
This also uncovered a bug in _parse_enc (basically, there can be
multiple character entries per line, so one needs to use `.split()`
instead of `.split("\n")`.

Because the previous version was buggy: on an encoding file like http://tug.ctan.org/info/fontname/8r.enc, you can see there are multiple entries per line (/.notdef /dotaccent /...) and lines are starting with a space, so the previous parser would fail immediately below when asserting that all lines start with a /, and even without the assertion, would misparse the file.
Sorry, something went wrong.
