Subject: libreadline4: ~ doesn't work in UTF-8 locale

Date: Thu, 02 Jan 2003 22:15:17 -0500

Package: libreadline4
Version: 4.3-4
Severity: normal

The ~ command should switch the case of the character under the cursor
like in vi.  With a locale like en_US it works.  However, with a
locale like en_US.UTF-8 it appends several non-printing characters
after the character under the cursor.

As an example, type the sequence abc at the bash prompt.  Then move
the cursor over the b and press ~.  Using readline's vi-mode I can
edit the command line in vim, which shows the current command line to
be aBðÿ¿c (it should be aBc).  (however, at the bash prompt the extra
characters appear as dotted boxes and the cursor moves unnaturally
over them).

reassign -1 bash
stop

Thanks to Chet Ramey for looking into this problem and sending me the
patch below.  It works for me, at least, and looks reasonable.  Since
bash includes the libreadline source directly, the patch must be
applied there as well as to libreadline.  (the details of the problem
are given in bug #175127, filed against the libreadline4 package)
