N3690 2.3 [lex.charset]/1 has a good caret but a bad tilde. The offending LaTeX is:
_ { } [ ] # ( ) < > % : ; . ? * + - / ^ & | @$\sim$@ ! = , @\textbackslash@ " '
so all occurrences of @$\sim$@ should be inspected.

2.13 [lex.operators] has a bad caret but a good tilde. The offending LaTeX is:

+ >- >* >/ >% >^{} >& >| >\tilde\br
PDF search indicates that there are 25 occurrences of this.

20.10.7 [bitwise.operations]/5 has a bad tilde. The offending LaTeX is:
\tcode{operator()} returns \tcode{~{}x}.
This appears elsewhere (e.g. /9).

This seems to be fixed.

I confirm that [lex.charset] and [bitwise.operations] are fixed.

However, [lex.operators] is unfixed. The ^ and ^= have weird carets. By weird/bad, I meant "doesn't copy into a plain text editor normally" (at least on Windows). Please consider reactivating this.

I think you need to replace

\^

with

\char`\^

However, since this appears in a few more places than the one listing mentioned here, we should probably create a macro for this and apply that consistently.

FWIW the "bad" one is U+02C6 rather than U+005E

Thank you! As someone whose job is copy-pasting from the Standard, I really appreciate this fix.
