Guess this had to happen... there was a discussion about manufacturers' sanity just yesterday...

@stambaughw @sethhillbrand are there still reasons not to include multibyte chars in symbol names or do you believe it's safe?

@G-Pereira how about calling them τ/2?

[sethhillbrand]

U+0C30 is in our standard font, so it should be no problem.

I want to suggest to add a translated version of MPN at the keyword field as pi120u30/1. I think this might ease the search process.

@G-Pereira one last change, parent symbol's name offset i think it is good to change to 20mil / 0.508mm

Hi, I already fixed that on a separate PR that already has been merged, check #2939

[G-Pereira]

@aris-kimi and @chschlue is this ready to merge?

[chschlue]

Yes, thanks.
