Adding UTF-8 support to rubies compiled through ruby-build25 Apr 2012
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.
CONFIGURE_OPTS="--with-readline-dir=/usr/local/Cellar/readline/6.2.2" rbenv install 1.9.3-p194
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
