Version: <= 4.4-alpha In bash's `help.def' builtin, wdispcolumn() is used to display `help' columns. It terminates the string at wcstr[width - 1], with a comment that assmues each wide character to be exactly one column wide.
This works fine with most languages where widechars are, actually, one column wide. But with East Asian languages, more specifically Chinese, Japanese & Korean, it would produce terrible results. Maybe bash should consult wcswidth(wcstr+1,displen), or get the `len' in wcsnwidth() changed to some additional int* argument to store it, and consider the the difference between the real width and displen. -- Regards, Arthur2e5 (0x222D7BDA)
