It matters for reading/writing code, having uniform syntax, but it hardly matters for a general user's usage (in fact, I'm just talking about an alias, and its not so troublesome).

And regardless, this special character issue likely exists for any character; I imagine few are consistent among all languages, appearing on all keyboards.

So its just a pick your poison and stick with it situation, and whaddyaknow, English is still the most common internet language, and perl/bash have already ensured that most programmers have had to deal with these characters for decades
