swift doesn't like extended UTF-8 in TMPDIR

[jhheider]

Build issues in SwiftFormat and xcbeautify; fix below:

          ok, this fixes it:

    - export TMPDIR=$(mktemp -d)

so, it's not liking, apparently, the extended unicode characters in the TMPDIR envvar. slightly gross. but an easy fix.

I should probs should just drop the unicode characters in general.

[jhheider]

Colons. They're valid on normal filesystems, but rarely used in URLs (and why would we ever include one in a package name?).

[mxcl]

we don't add a colon deliberately. I didn't see an example of the failing TMPDIR in the attached link. Can you provide?

[jhheider]

you can get it locally easily enough (just comment out that one-line patch). here's an example in GHA: https://github.com/pkgxdev/pantry/actions/runs/7455318137/job/20284215852

[mxcl]

TMPDIR=/Users/builder/actions-runner/_work/pantry/pantry/homes/tuist.io∕xcbeautify-1.4.0/tmp

there’s no colon in that. I'm confused about the reference to colons I guess.

[jhheider]

sorry; was recommending regular old ASCII colons instead of fancy UTF-8 ∕.

[mxcl]

oic. We should use a standard character. I may just switch to actual folders it's not that onerous.

[jhheider]

yeah, the only issue with folders is variable number of path elements, which the UTF-8 slash nicely bypasses. not impossible to work with, but something that's been mildly annoying in the past.

I note that you have hardcoded +brewing in the pantry now. I was going to change the + to something that doesn't break regexes.

The examples that hardcode +brewing have no comments so I don't understand what is happening or why.

Please open tickets on brewkit, I cannot make brewkit more robust if all the fixes are one-off hacks in the pantry. Thank you.
