In an effort to support utf8-encoded grammar files, I tried the
following:
$ svn diff compilers/pge/rulec.pir
Index: compilers/pge/rulec.pir
===================================================================
--- compilers/pge/rulec.pir (revision 11998)

.local pmc infh
infh = open infile, "<"
+ push infh, 'utf8' # assume utf8, should degrade nicely for ASCII
unless infh goto ERR_NO_INFILE
.local string source
Which lets "make test" for parrot succeed just fine…
This generates a build error with punie, however:
../../parrot ../../compilers/pge/rulec.pir --output=lib/
punie_grammar_gen.pir lib/punie.g

Clues welcome.
