>The current vCard and iCalendar standards
([<A
HREF="bibliography.html#BIB-RFC2426"
>VCARD</A
>,
<A
HREF="bibliography.html#BIB-RFC2445"
>ICAL</A
>]) suggest the use of UTF-8
([<A
HREF="bibliography.html#BIB-RFC2279"
>UTF-8</A
>]) as default encoding for
vCard and iCalendar files. Since UTF-8 is the only portable way to
store internationalized files, it is used by default by Libmimedir
when files are saved. On loading, an UTF-8 encoding is assumed, if
the encoding is not settable in the loading function. (The various
load_from_channel functions define the encoding implicitly through
the channel's encoding.) If the input is not in UTF-8, a conversion
error will be returned.</P
><P
>The two functions
mimedir_vcard_read_list()
and
mimedir_vcal_read_list()
are special cases; they open a file, first assuming it is in UTF-8
encoding. If the file contains invalid UTF-8 sequences, a second try is
employed, using the current locale. If this fails, too, a third and final
try is made, assuming the file is in ISO-8859-15 (aka ISO Latin 9)
encoding.</P
