Nano-tiny (e.a) vs libslang-utf8

[Jan Vroonhof <jvlists@ntlworld.com>]

First of all I can confirm this happens with 1.0.6-2 as well.

In fact I tried doing this in all slang based editors I have installed.

I tried two tests


1. Loading the following file

/tmp/nano-1.1.5> LANG=C less /tmp/testje
"/tmp/testje" may be a binary file.  See it anyway? 
pond<A3>pond

The <A3> is the latin-1 UK currency symbol

gives
  nano-tiny & jed : Only "pond" visible
  ae : Shows "pondpond" (see also below) + keyboard shortcuts only partly visible.

2. Insert a high-bit character

nano-tiny & jed : show only characters upto high-bit character on that
line. Rest invisible (but cursor moves normally), saving the file
gives the expected results (with all the invisible characters)
   
ae: Displays as if the high-bit character was moved to the end and replaced
by space[1], i.e. if C represents the cursor then the file from 1 is shown as

pondpond C

I would suggest slang1-utf8 is broken (see also bug#128255 and bug#129415) and suggest

retitle 129694 UTF8 slang breaks editors
reassign 129694 slang1-utf8
merge 129694 128255 129415

P.S. Using unicode enabled shells or setting various locales does not make any difference.

Footnotes: 
[1]  i.e. it filters it out when displaying, but does let it count when doing cursor positioning.
