Subject: font-reduce.py: Add special space handling
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=b5e8f2fd73acac1831d341df74a98e65e5829ba3;p=mw2txt.git

font-reduce.py: Add special space handling

For some reason, FontForge doesn't like selecting spaces with
`select(('ranges',),...)`.  No idea why, but this works around the
problem.
