As cygcheck is a Windows msvcrt.dll program, not a Cygwin cygwin1.dll program,
it uses Windows popen which runs commands under $COMSPEC rather than $SHELL, and
that can be affected by {HKLM,HKCU}/Software/Microsoft/Command Processor/
registry entries e.g.:

$ regtool list -v /proc/registry/HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Command\
Processor/
DefaultColor (REG_DWORD) = 0x00000000 (0)
EnableExtensions (REG_DWORD) = 0x00000001 (1)
CompletionChar (REG_DWORD) = 0x00000040 (64)
PathCompletionChar (REG_DWORD) = 0x00000040 (64)
$ regtool list -v /proc/registry/HKEY_CURRENT_USER/SOFTWARE/Microsoft/Command\
Processor/
Autorun (REG_EXPAND_SZ) = "@chcp 65001 >nul"
CompletionChar (REG_DWORD) = 0x00000009 (9)
DefaultColor (REG_DWORD) = 0x00000000 (0)
EnableExtensions (REG_DWORD) = 0x00000001 (1)
PathCompletionChar (REG_DWORD) = 0x00000009 (9)

runs chcp 65001 at cmd startup, but could also do much more and different.
