The rightmost column -(which would be ASCII in a regular hex dump) shows one Unicode -character for each UTF-8 sequence in the dump. - -Unicode sequences in the hex column are color-coded to match their -character in the right column. Colors alternate between a set of 4, -to help keep track of which character goes with with byte sequence. - -Sample output: - -00000000: 41 e2 98 af e2 98 ae c2 bf c3 a1 e2 88 9e 42 0a A☯☮¿á∞B↵ -[colors] 1 2 3 4 1 2 3 5 12341235 - -; 0 black (don't use) -5 = 1 red -1 = 2 green -4 = 3 yellow -; 4 blue (don't use) -2 = 5 purple -3 = 6 cyan -; 7 white (don't use) - -Colors 1 to 4 are used for successive Unicode characters. For -instance, color 3 is used for the ☮ character, and also for its hex -representation "e2 98 ae" in the dump. Note that the "A" and "B" are -in the ASCII subset of Unicode, and are treated as one-byte sequences. -If there's a BOM, it'll be in reverse video color 1 (green), and the -printable form of it will likely be "BOM". - -Color 5 is for unprintable characters, with Unicode codepoints below -0x20 (aka "control characters"), plus a few others like 0x7f (delete). -↵ is used for newlines... note that an actual ↵ character will -also be displayed as ↵, but in one of the 4 alternating colors. - -Not shown in the dump: byte sequences that have the high bit(s) set, -but are not valid UTF-8, will be shown in color 5 (red), but in -reverse video. - -Usage: uxd [options] [<filename> ...] - -Options should be based on xxd(1) options, though not all of them will -be supported. If uxd-specific options exist, they should ideally use -letters that xxd doesn't, to avoid confusion. - -Ideas: -support other encodings for Unicode, like UTF-16? +See uxd.rst for full documentation, or (after installation), "man uxd". |
