Package: nano
Version: 1.2.4-5
Severity: normal
Basically for the records as I fear this cannot be cured:
Using nano in Debian stable after enabling utf-8 I found that I can type
and see lowercase umlauts quite well while uppercase prints garbage.
strace helped to locate the problem (several lines striped)
1. Entering lowercase a umlaut
ä = codepoint \x00e4 = utf-8: \xc3 \xa4 = \303\244
read(0, "\303", 1) = 1
write(1, "\303", 1) = 1
read(0, "\244", 1) = 1
write(1, "\244", 1) = 1
2. Entering uppercase A umlaut
Ä = codepoint \x00c4 = utf-8: \xc3 \x84 = \303\204
read(0, "\303", 1) = 1
write(1, "\303", 1) = 1
read(0, "\204", 1) = 1
write(1, "^\304", 2) = 2
^^^^^
That's somewhat funny: \x84 is considered a control character and thus
replaced by its value+64 and preceeded by a mark. This completes messes
utf-8 since the two-character-sequence gets broken.
While such an approach works quite well in iso-8859-x it should already
cause trouble in KOI8-R since the \x80-\x9f positions are printable
characters in that table (see RfC 1489).
Unfortunately, cleaning up is_cntrl_char in utils.c is not enough as
there's appearently another escaping within slang that translates
"\303\204" into "\303~D". I'll try to isolate this as a bug in slang1 if
time permits.
The whole problem went away in etch (currently 1.3.8-2) so probably the
pressure to fix this in sarge is rather low. Those who want to backport
and lose the Debian stable security: Download the etch version of dpkg,
build it, install dpkg and dpkg-dev. Download and build slang2, install
libslang2-dev. Then the build dependencies for nano are met. The
resulting nano_*.deb can be installed on any sarge system, no hassle
with dependencies.
