Mirrors MC's boxes.c::display_bits_box
(mc/source/src/filemanager/boxes.c:955-1004). MC exposes 4 modes
(UTF-8, Full 8 bits, ISO 8859-1, 7 bits); TLC is UTF-8 throughout
so we expose the relevant 3-state subset:
- Full 8 bits: bytes pass through verbatim
- 7 bits: high bit stripped (parity-stripped serial consoles)
- UTF-8 (validated): pass through UTF-8, ? for invalid
New file: src/filemanager/display_bits_dialog.rs
- DisplayBits enum with 3 variants
- DisplayBitsDialog (radio-list, mirrors SortDialog)
- from_config() / map_byte() / is_valid_utf8() helpers
- 12 unit tests
New DialogState variant:
DialogState::DisplayBits(Box<DisplayBitsDialog>)
Wired into dispatch (handle_key), render, is_finished (false;
the dispatcher captures Confirm/Cancel from handle_key), title.
Tests: 1318 passing (was 1306; +12 new).
