Subject: Fixup config.w32.
X-Git-Tag: PRE_NEW_OCI8_EXTENSION~278
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=57ae2f99b70867b10eae0492ae0d4670cb15018b;p=php

Fixup config.w32.

Implement unicode_decode() and unicode_encode(), as described in README.UNICODE.

Still need to decide how to handle errors here, since there is no error return,
and a conversion error is not necessarily fatal.
