Ruby 1.9.1 has been out for a long time now, so you may feel pretty comfortable about installing it on your box and doing to the big “let’s see what this broke” game with Rails. We’ll I just wanted to give you a little heads up with another program you may have not expected issues with, Textmate.
What? The Horror! Not being able to code Ruby with Textmate. Well, fortunately, that is not entirely true. You can still use the infamous editor to edit you Ruby code, no problem. The issue comes when trying to use any of the generators or functions that require you to execute Ruby code. You may find yourself running into this puzzling error:
invalid multibyte char (US-ASCII)
For those of you not in the know, the handling of different character types have changed in Ruby 1.9 and Textmate’s latest release does not accommodate this change.
I will update this with any updates, in terms of fixed Textmate versions or any other reliable solutions.
