Re: [Boost-users] UTF-16

22 Jul 2009


      Problem with that is that std::string::length() no longer provides a
meaningful value. It will count each byte is 1 character.

Hi
My approach is using std::string, etc. all the time and using UTF-8
internally, only converting to other charsets when it's needed.
I use IBM icu library and made a boost::iostreams filter to convert
encoding, once it's done takes a lot of complexity away, I use it like:
// setup a conversion from charset to utf-8
          filt_streamb.push(ucnv_filter(charset.c_str(), "utf-8"));
          istream is(&filt_streamb);
Perhaps there's interest to push this charset conversion into
boost::iostreams filters examples.
Regards.

Oh, I also forgot to mention, I am also using boost::filesystem::path. I
guess this means I need to use wchar_t everywhere (std::wstring,
boost::filesystem::wpath, etc) and just let wxWidgets do the
encoding/decoding? If I don't have to do any encoding/decoding myself,
then
there really is no need for a special object. But just in case I would
like
to have the encoding/decoding abilities.

Hi everyone,
I did a bit of googling to see if Boost 1.39 as any portable support for
UTF-16 encoded strings, but I did not find any. I'm currently using
wxWidgets in my application, and I need a decent string object to use. I
know that wxWidgets has UTF-16 string support through wxString, however I
do
not want to expose this object in my interfaces. I want to remain as
abstracted away from wxWidgets as possible. Having said that, if someone
could tell me if there is any existing UTF-16 string support in Boost,
I'd
appreciate it. I did not find anything in the vault, sandbox, or trunk in
Boost.
If boost has no such string object, could someone give me a head start on
where to look? Thanks.
