|Not -1 otherwise oub will not be NUL-terminated and end with junk:

Sure thing. Just like below. Normally stack pages are cow forked
from zero if i understand that right. But maybe i do not.

|Throws 1 because you need "utf-8", but with it, see above.
Well names and iconv are a thing. Especially regarding Unicode
(and nl_langinfo(CODESET), if i remember UnixWare right).

|Citrus iconv agrees. Its manpage says:
|
| If the string pointed to by *src contains a character which is valid
| under the source codeset but can not be converted to the destination
| codeset, the character is replaced by an "invalid character" which
| depends on the destination codeset, e.g., '?', and the conversion \
| is con-
| tinued. iconv() returns the number of such "invalid conversions".
That was my thinking.
Thanks for confirming this.
