Rollup merge of #114377 - Enselic:test_get_dbpath_for_term-utf-8, r=thomcc

test_get_dbpath_for_term(): handle non-utf8 paths (fix FIXME)

Removes a FIXME for #9639

Part of #44366 which is E-help-wanted

The remaining two FIXMEs for #9639 are considerably more complicated, so I will create separate PRs for them.
