entire status outputs literal ←[ instead of ANSI escape codes under TERM=cygwin

[eratolekov]

What happened?

Summary

When TERM=cygwin, entire status (and likely other commands) writes the Unicode character U+2190 LEFTWARDS ARROW (UTF-8 e2 86 90) instead of the real ESC byte (0x1B) when emitting ANSI escape sequences. As a result, the terminal shows literals like ←[32m●←[m instead of colored output.

Environment

• OS: Windows 11
• Shell: Cygwin bash (/usr/bin/bash)
• Terminal: WezTerm
• TERM=cygwin
• TERM_PROGRAM=WezTerm
• entire version:

Diagnostics

The same environment renders ANSI from other tools correctly, so the
terminal/ANSI pipeline is fine:

$ ls --color=always | head -3 | xxd | head -2
00000000: 1b5b 306d 1b5b 3031 3b33 346d 646f 636b  .[0m.[01;34mdock
00000010: 6572 2d63 6f6d 706f 7365 2d64 6576 1b5b  er-compose-dev.[

ls emits proper ESC 0x1b. WezTerm interprets it as expected.
