Hi!

Quite a while ago we have accepted the “Use default_charset As Default
Character Encoding” RFC[1], which also contains the clause “Old
iconv.*/mbstring.* php.ini parameters will be removed for master PHP6”
(obviously that was written before we decided to skip PHP 6, and as such
would have to be applied to PHP 7).  I'm quite happy, though, that this
hasn't happened yet, since it seems that the encoding names may be
different between the extensions.  At least the php.net manual states[2]:

| Some systems (like IBM AIX) use "ISO8859-1" instead of "ISO-8859-1" so
| this value has to be used in configuration options and function
| parameters.

It appears to be worthwhile to review the deprecation of the respective
iconv.* ini options.  Not quite sure about the mbstring.* ini options.

Also, if we stick with the deprecation of the iconv.* ini settings, we
also should deprecate iconv_set_encoding(), which currently changes the
deprecated iconv.* ini options, and as such throws a deprecation
warning.  However, if the ini options would be removed, what should the
function do?  Nothing?  Change the php.*_encoding settings.  In my
opinion, both would be rather confusing.  iconv_get_encoding() has a
similar, albeit minor, issue.
