... it just beat me again in a subtle case, and AFAIR it's not the
first time LANG is discussed:

Using LANG=C (what is sometimes useful), gn_char_get_encoding() is
initialized to ANSI_X3.4-1968 and that's the charset chosen to treat an
input vcard file... so obviously char_mbtowc() fails (with an UTF-8 vcf).


It could be good to write it down somewhere so that other people could
understand:
$LANG not only affect the gnokii output language, but *also* the way it
treats input files (what IHMO isn't appropriate ;))
