As discussed in #679, add
configure --with-icu
to compile with support for libicu, and as an example, changecontains_uppercase()
to Unicode-awarestring_contains_uppercase()
.The pros of libicu are that it is deep, complete, well-tested, and up-to-date.
The cons are that it contains multiple overlapping/conflicting APIs, and that UTF8 is generally treated as second-class compared to UTF16.
In the example function we are able to use one of the UTF8-specific APIs cleanly without recoding.
Linking with libpcre might also be required to get utf8-aware search. libicu knows about regular expressions but only exposes an interface for C++ and Java.
