This should finally take care of the whole find µ vs u issue

[hotdogman]

This was accomplished using the following one liner
find * -type f -exec grep -Il . {} \; -exec sed -i 's/µ/u/g' {} \;

This should work fairly well, but it might break a few things, specifically the uBlock privacy filter list, and maybe the chinese translation URL.
Please review before blindly merging.

I don't plan to introduce such an amount of code change noise just for the sake of that u. We are not dealing with a showstopper here. And whatever is left in text files can be taken care in the long run, and this will be done on Crowdin, or else that will double the amount of work.
