I guess that the current behaviour needs to be retained in some form, > because clients will rely on it. Correct. And GNU libiconv (a different implementation of iconv, for systems that have a deficient iconv implementation) implements the same behaviour. > 2. However, the current behaviour is a problem for portable programs like > Recode, that need to work with multiple iconv implementations. If you need code that works with multiple iconv implementations, take a look at gnulib/lib/unicodeio.c lines 137..154 or gnulib/lib/striconveh.c lines 950..962. You see that the problem is that replacing unknown or inconvertible inputs with '?' or '*' or NUL is - just not yielding practically useful behaviour (especially because the caller then cannot transform a buffer all at once, a purpose for which the iconv function was initially designed), - requiring platform dependent recognition heuristics. -- You are receiving this mail because: You are on the CC list for the bug.
