Convert Char String to utf16 format - C++ Solaris

[Kambam, Siva (Midwest Success LLC)]

Hi ,
I need to convert a char string in to a utf16 format.
I downloaded the API from
http://icu-project.org/apiref/icu4c/ and build it on Solaris

I am using the following function to convert the input char string to unicode format

Chat inputString[10];
Strcpy(inputString,"test);

UnicodeString* unicode = new UnicodeString(inputString).

I think the input string is convert in to unicode format.

Now What I need is convert the unicode in to   utf16 format.

1. ) Is there  a way that I can convert the Char string in to utf16 format in C++ ( gcc )
2. ) Do I need to convert the char string in to unicode and then convert it in to utf16 format ?
3. ) Does the UnicodeString* unicode = new UnicodeString(inputString) get the required utf16 format ?

Thanks in Advance,
Siva .

My understanding is that ICU uses UTF-16 as internal encoding. See http://www.icu-project.org/userguide/strings.html#strings

Thanks for the reply.

Also after converting the char string to unicode is there a function to display the unicode to the console  ?

The code snippet you showed will work because of a "feature" recently discussed whereby the constructor of the UnicodeString class will use the default system code page to "widen" the "narrow" string AND because the data you gave in the example is Ansi and the default code page (on most people's systems) will likely "widen" that string correctly to Unicode.

 

However, if you are using a non-Standard encoding for the text (e.g. anything non-Roman/Ansi/Ascii) OR if your default system code page on a user's machine is not the same as the encoding of the data, then this won't work.

 

You need to clearly separate in your mind the conversion from "narrow to wide" (which is happening by virtue of the UnicodeString constructor for narrow strings and which uses the default system code page) and the conversion from some encoding to Unicode (or UTF-16 as you call it).

 

For the data you showed (i.e. "test"), those two conversion are probably the same; but that may not always true depending on the encoding of your data.

 

Bob

If you've compiled ICU to use a .dat archive or individual data files, you
can modify ICU's data after installation.  This is done with
--with-data-packaging=archive and --with-data-packaging=files
respectively.  Since you mention DLLs, I presume this is Windows.  You can
use the Cygwin/MSVC configuration to get that configuration for the data
easily.  You can also do this through the standard project files, but it's
a little more difficult because it requires a little more knowledge about
how ICU is built.

The .dat archive can be modified in its installed location with icupkg.

If you compile ICU's data into a DLL or a static library, the files can't
be changed after the installation, unless you rebuild the data and
reinstall a brand new data DLL.

More details on packaging ICU's data can be found at:
http://icu-project.org/userguide/icudata.html
