What I think could be done is * Add "//UTF-8 chars" comments to testmodule.d and ufcs.d; mangle.d already has one. * Make gdc-utils.exp (gdc-convert-test) check for those annotations, adding // { dg-require-effective-target ucn} if found. The new annotations would have to go upstream, I believe. WDYT?
