[MacRuby-devel] macruby produces strings with encodings that differ from MRI
Code
ABC='ABC'
puts "ABC[0] encoding is #{ABC[0].encoding}"
puts "?\\xff encoding is #{?\xff.encoding}"
Output
MRI output
ABC[0] encoding is US-ASCII
?\xff encoding is ASCII-8BIT
macruby output
ABC[0] encoding is UTF-8
?\xff encoding is UTF-8
The encodings reported above did not seem to be effected by the encoding of the
source file. I tried both ASCII and UTF-8.
When the same code is executed in (mac)irb the results are the same for macirb
as they are for macruby.
irb for MRI however produces UTF-8 strings in both cases! This seemed very odd
but I'm fairly sure it's because I have an environment variable:
LANG=GB.UTF-8
When I changed to LANG=GB.US_ASCII irb for MRI rendered 'abc'[0] with US_ASCII
encoding. macirb still used UTF-8.
(I discovered this when trying to get ruby-mysql to work with macruby. It
doesn't work as-is but seems to work with a few mods that use force_encoding to
make MRI and macruby produce the same outputs).
I abandoned my earlier attempts to use postgres with macruby via the pg gem.
It failed regularly but in unpredictable ways associated, as far as I could
tell, with memory management problems.

Hi,
Maybe related to http://www.macruby.org/trac/ticket/742.
MacRuby ignore magic-comment, and uses default encoding UTF8.
Thanks.

Re: [MacRuby-devel] macruby produces strings with encodings that differ from MRI
Yes, looks like the same issue as ticket 742. I did look at tickets but
failed to spot that.
The comment on the ticket re only UTF-8 being required may be true - it
certainly is for me. Sadly the ruby-mysql gem works in such a way that the
difference between MRI and macruby breaks it.
