Typing special characters in links breaks them

In my post linked above, the presence of the character ó beaks the link at the end. I can't seem to figure out how to fix it. This of course, makes linking to websites written in or about subjects related to languages that use diacritics very messy.

You need to URl encode the text. This link works:

Just google "URL encoder"
