Created attachment 508792 [details] emerge --info '=dev-libs/beecrypt-4.2.1-r4::gentoo' beecrypt fails to compile, centered around invalid conversions involving char16_t . I don't know if this caused by the version of gcc I'm using, by the 13.0 -> 17.0 profile change, or by a change to one of its dependencies.
