[Caml-list] utf-16 string operations

[Michael]

What is the prefered way of doing string operations with utf-16 strings?
Say, I have a utf-16 coded string and want to do some search/replace
operations on it. What is an easy way of doing this?

Does batteries include functions for doing this? Allthough reading
through the docs I don't see it.

thanks for answering

Search/replace is a bit unspecfic. But normally, it is best to convert  
to UTF-8, and do the operations then. UTF-8 has the advantage that it  
is compatible to many algorithms working byte by byte, i.e. normal  
string operations like substituting a given string by another one, or  
comparing strings.

Conversion support is available e.g. in Camomile, but also in Ocamlnet.  
Camomile has also some direct support for manipulating UTF-16 strings  
encoded as int array (if you need to go down that far).

pcre-ocaml supports regular expressions for UTF-8 strings.

thanks for the help.
The conversion with ocamlnet was the mising hint.

Maybe Search/replace is a bit unspecfic, but it's exactly that:

- Str.global_replace (regexp "string") "newstring" utf-16-string
