The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=c2ba66d4d01f23303352bfe3cbd50ff5d9a05947 commit c2ba66d4d01f23303352bfe3cbd50ff5d9a05947 Author: Warner Losh <imp@FreeBSD.org> AuthorDate: 2024-11-02 22:02:44 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2024-11-02 22:02:44 +0000 loader: Fix boot menu on BIOS Only the gfx-enabled boot loader supports unicode. Otherwise, we have to use the old cons25 / ibmpc upper code page drawing characters. Check to see if we have the gfx.term_drawbox function. If we do, we support the unicode drawing characters. If we don't, then we have an older loader that doesn't support it *OR* we have the reduced function, text-only boot loader. In either of those cases, we need to use the old graphics characters. Abstract all those details into core.hasUnicode function.
