unconvertable chars display glitches

[Alain Bench]

Hello,

    Testing Debian Woody Glibc iconv 2.2.5 and GnuPG 1.4, /René Lecœur/
made a test key (comes here attached). His UID contains 2 well-formed
UTF-8 special chars: An 'é' (e acute) and a 'œ' (oe ligature). Perfect
display in a locale having both chars, like with CP-1252 charset:

| $ gpg -vvv --list-keys "René"
| gpg: using character set `CP1252'
| gpg: using PGP trust model
| pub    512D/882B59FD 2005-01-08
| uid                  René Lecœur <joe at foo.bar>

    But in a locale where only the e acute exists, like with charset
CP-857 (Turkish):

| $ gpg -vvv --list-keys "René"
| gpg: using character set `IBM857'
| gpg: using PGP trust model
| pub    512D/882B59FD 2005-01-08
| gpg: conversion from `utf-8' to `IBM857' failed: Invalid or incomplete multibyte or wide character
| uid                  RenÚ Lec\xc5\x93ur <joe at foo.bar>

 - The warning line about failed conversion may perhaps not be really
necessary in such simple unconvertability case: The \hex display of raw
UTF-8 may well be sufficient?

 - The 'Ú' (U acute) in place of 'é' in "René" is wrong. Fallback to
Latin-1 conversion of full string if one char only was unconvertable
seems not optimal here.


     Probably a display like that might be clearer:

| $ gpg -vvv --list-keys "René"
| gpg: using character set `IBM857'
| gpg: using PGP trust model
| pub    512D/882B59FD 2005-01-08
| uid                  René Lec\xc5\x93ur <joe at foo.bar>


Bye!	Alain.
