If I had to point one thing that gives me true headaches, I would certainly choose encodings. I have already spent a lot of time dealing with encoding problems and I usually get stressful when a have to deal with a new one (I think it is common sense to suppose that everyone would prefer spending time dealing with other things instead of encodings).
So, last week I was using
pry to prepare a small course about Ruby and I found out that I couldn’t input UTF-8 characters. When trying to insert a
á I was getting this unicode character code:
After a quick glance in some search results for irb utf-8 problem, I discovered that I was having this problem due to a Ruby compilation without Readline (which is a library with some useful functions for command lines).
Fixing this was really simple due to the possibility of passing options to include on Ruby compilation on
ruby-build. So it was only a matter of executing this line to recompile and reinstalling Ruby with Readline support.
Of course, if your readline dir is somewhere else, please put the correct directory instead of the one I put there.
pry started to accept UTF-8 characters.
UPDATE: Fixed some grammar issues.
UPDATE II: I’ve put a better picture for the solution
