Not disagreeing with the sentiment, but if you’re using Windows, Linux, or OSX, you do have a searchable character map. That fails when you don’t know the name of the character, in which case you can use something like Shapecatcher (http://shapecatcher.com/ http://shapecatcher.com/), but then how do you know whether it’s a Greek theta or a Coptic thethe or a Cherokee na or Cyrillic fita or Latin barred O? Clearly our editing powers need to improve if we’re to feasibly use non–English-alphanumeric variable names.
