But tr/// is faster than s///, and also, not all characters with diacritic symbols are equal. For example, simply substituting "A~" with "," and "E`" with ",", means that "Sera'" and "Sere'" would both turn into "Ser,", and both be sorted as equals. That's probably not desired behavior.

In other words, simply turning anything "ugly" into a comma will lose important information needed for an accurate sort.

Remember that tr/ABC/A/ turns A, B, or C into A. It's the same as tr/ABC/AAA/. So in my example, I'm turning all of the "e"-like characters with diacritic symbols into an 'e'. I'm also retaining the original string so that in cases where Avo^ and Avo' would be sorted as equals, a defined order is retained.
