"u" has the advantage of correctly rendering basically everywhere, which"μ" does not. My initial attempt to share this was automatically corrected to "Mlauncher" for example. I'm pretty sure this is the reason the one symbol is used so often where it should be the other.

The solution is just to stick to the Latin alphabet, but you can't deny that mixing in a little Greek every now and then is fun.
