Sorry, something went wrong.
…ox (pythonGH-152451) Textbox mangled non-ASCII characters of an 8-bit locale encoding: it masked reads with curses.ascii.ascii(), which clears the 8th bit, and tested input with curses.ascii.isprint(), which rejects bytes above 127. Decode cells and input bytes with the window's encoding instead. Cells are read with instr() and the lower-right cell is written as text, since inch() and insch() with an int byte mishandle a non-ASCII character on a wide build. This uses only the byte-oriented curses API, so it works without wide-character support.

with curses.ascii.isprint(), which rejects bytes above 127.
Decode cells and input bytes with the window's encoding instead. Cells are
read with instr() and the lower-right cell is written as text, since inch() and
insch() with an int byte mishandle a non-ASCII character on a wide build. This
uses only the byte-oriented curses API, so it works without wide-character
support.
