Hi,

Not sure if this is helpful, but I get a very similar error when trying to build the nokogiri gem with RVM & ruby 2.0 on my Mac OS X 10.6.8 machine. I'm not at that machine currently, but I can post the error if you think that will help. 

Best,
Mica

It seems a problem in a ruby file in MacTeX 2013. Can someone help me
get this working?

Maybe something utf in the latest ruby ... can you try to replace the \xFF with \xFFFC and see what happens?

Same thing happens. Now it says \xFFFC is an invalid multibyte escape

it runs ok with \xFF here in 1.9

in 2.0 i need to patch in that file:

series.each_char do |key| # was .each but there is no alias to each_char any longer

does the top of switch.rb mention:

#encoding: ASCII-8BIT

(i do have a prototype of texexec in lua but no time to finish that now but i fear at some moment i have to do it as i cannot foresee ruby 2.0 compatibility issues)
