Hi Source of the previous problem was the encoding. test.rb: # encoding: US-8859-1 p \_\_ENCODING\_\_ # says UTF-8 !?!??? ...gsub(/ü/,...) # failure The sourcefile is ISO-8859 (because of bad editor) - (( I want to solve the ruby-problem, but if we have vi-experts: after :set enc=utf8 :x the file is still iso?! )) How can I input an Umlaut, or can get rid of "invalid multibyte char (utf8)" Datafile is in utf-8, so the error comes from the source. Google tells much of Ruby 1.9, but all that didnt help. Thank you Berg ---

Search for "vim save with new file encoding" or similar.

No, what it actually should say is   unknown encoding name: US-8859-1 (ArgumentError) Please, do not post pseudo code with typos in it (it's ISO-8859-1), but actual working code that we can simply copy and paste to verify your problem. > ...gsub(/ü/,...) # failure I can not reproduce a failure. Again: please show the \*actual\* code and the specific error message.

Hi thats because I cant copy&paste... x.rb: !#/usr/bin/ruby # Encoding: xxx # encoding=xxx p \_\_ENCODING\_\_    # shows "#\" (and no error)    # Ruby version 2.3.0 Sure you'll get the same results... ./x.rb irb works as expected, mri not. Berg ---

No! I already said it works fine for me (using 2.3.0). Note that the shebang line in your code is wrong; you really shouldn't expect us to try and figure out what your problem is when you are too careless or lazy to post the correct code. And get a proper mail client and/or editor or whatever it is that doesn't allow you to copy&paste or you'll never be able to work productively.
