Merge pull request #16784 from bradcray/chplspell-updates
Updates to chplspell
[reviewed by @cassella]
I didn’t want the belated merging of Paul’s PRs to have him be behind
again on day 1, so ran chplspell myself for once. Turns out that due
to something (probably the Python 3 updates), we’re now getting
mis-spellings on unicode characters.
