idna_to_ascii_lz success even if no conversion to current locale

[Ray Satiro]

Hello,

I notice that idna_to_ascii_lz can return success even if the string 
could not be converted from the current locale due to being built 
without libiconv [1][2], and that doesn't appear to be documented. The 
result appears to be libidn without libiconv treats the locale encoded 
string as utf-8 and attempts to convert from utf-8 to punycode. Could 
someone explain if that is intended or not and whether there are any 
implications I should look into.

I am not subscribed to this mailing list so please CC me on reply. Thanks
