The report's built-in Helvetica is WinAnsi-only. These fonts cover what
the report can carry: ReportSans (Noto Sans plus the arrows and
mathematical operators of Noto Sans Math; Latin incl. Extended-A/B,
Greek, Cyrillic) in regular, bold and italic, and ReportSansKR, the same
plus Hangul from Noto Sans KR, in regular and bold.
scripts/build-pdf-fonts.py rebuilds them from the upstream sources. All
are SIL OFL 1.1; the licence sits beside the files. The directory is
named in outputFileTracingIncludes because the renderer reads the files
by a path the tracer cannot follow.
