--- Comment #8 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Note that section 3.1 ("File Format" > "General") specifies:
"A SARIF log file SHALL be encoded in UTF-8 [RFC3629]."
https://docs.oasis-open.org/sarif/sarif/v2.1.0/sarif-v2.1.0.html
Though I suppose it would be possible to escape non-ASCII chars so that the
.sarif file could use the ASCII subset of UTF-8, if there's no other way around
this from the DejaGnu side.
