Lob 6.0.3: Various warnings when running tests and loading library

[broksonic21]

Lob 6.0.2 fixed a bunch of warnings, but these appear back in Lob 6.0.3:

warning: character class has '-' without escape

#209 has more info on the original fix.

You can see the regression here, amongst other lines:
v6.0.2...v6.0.3#diff-394b2cc6b345c7ebd5c1693dcd21d403a6c17b95200e382fe646878a708ce963R260

At minimum, I am seeing it here in our app:

fyi @siddharthpant92 (as author of 6.0.3) and @BennyKitchell (as maintainer on 6.0.2 fix)

Hey @broksonic21 Thank you for bringing this up. Hopefully his has been fixed in #221.
I can close this issue out once you confirm or if we don't hear from you soon.
Sorry for having those warnings re-surface

Yep, this worked for us - thanks!
