[MacRuby-devel] macruby produces strings with encodings that differ from MRI

[Watson]

Hi,

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

Thanks.

> 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.
