From 994a2196745637fd0805132711b1ed9354b75426 Mon Sep 17 00:00:00 2001 From: salmonik Date: Fri, 31 Jul 2026 17:28:31 +0200 Subject: vt: decode UTF-8, render box-drawing/arrow glyphs procedurally MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The editor's gutter '│' (U+2502) appeared as '???' — write_bytes fed each UTF-8 byte to the state machine, which mapped every byte >= 0x80 to '?', and the Latin-1 font has no box-drawing glyphs anyway. - vt.write_bytes now decodes UTF-8 sequences; printable non-ASCII dispatches to the glyph path instead of the byte parser. - gop: unicode_glyph_bits() procedurally rasterises box-drawing (U+2500-257F light/heavy/double), arrows (U+2190-2193) and the em dash (U+2014) — pure geometry, no font data needed; blit_glyph falls back to it for ch >= 256. Verified via framebuffer dumps: editor gutter │ renders as a vertical line, help screen ═ separators and ←→↑↓ all render as lines (no '?'). Shell banner em dash renders too. --- shell/src/lib.rs | 1 - 1 file changed, 1 deletion(-) (limited to 'shell') diff --git a/shell/src/lib.rs b/shell/src/lib.rs index ec2474d..4601b98 100644 --- a/shell/src/lib.rs +++ b/shell/src/lib.rs @@ -279,7 +279,6 @@ fn cmd_hexdump(args: &str) { } } - // --------------------------------------------------------------------------- // edit — run the built-in editor (rsdosedit) on a file // --------------------------------------------------------------------------- -- cgit v1.2.3
