[Terminal] repeated characters are not displayed correctly via ncurses

Description

Terminal does not display repeated characters correctly when using ncurses6, instead squashing them down to a single character, when using the default xterm-256color terminal type (TERM env variable).

I'm seeing this with R1/beta2 on x86_64, but also checked the latest nightly (hrev54840) and got the same result.

The attached program, compiled with gcc curses_test.c $(ncurses6-config --cflags --libs) , will print just a single "A" rather than the expected "AAAAAAAAAA". (ncurses6-config --version reports 6.2.20200212.)

Note that if TERM is set to xterm-color everything works correctly.

Maybe the underlying issue is ​https://invisible-island.net/ncurses/ncurses.faq.html#xterm_generic ? i.e. ncurses6 uses the ECMA-48 REP character since xterm-256color says it's supported but Terminal does not implement it?

Indeed, it seems highly probable that this needs to be implemented.

Yes, checked the source, it isn't.
