uciter8: Lenient reading of 8-bit Unicode with a UCharIterator
This sample demonstrates reading
8-bit Unicode text leniently, accepting a mix of UTF-8 and CESU-8
and also accepting single surrogates.
UTF-8-style macros are defined as well as a UCharIterator.
The macros are incomplete (do not assemble code points from pairs of surrogates)
but sufficient for the iterator.
If you wish to use the lenient-UTF/CESU-8 UCharIterator in a context outside of
this sample, then copy the uit_len8.c file,
as well as either the uit_len8.h header or just the prototype that it contains.
*** Warning: ***
This UCharIterator reads an arbitrary mix of UTF-8 and CESU-8 text.
It does not conform to any one Unicode charset specification,
and its use may lead to security risks.

To Build uciter8 on Windows
1. Install and build ICU
2. In MSVC, open the workspace file icu\samples\uciter8\uciter8.sln
3. Choose a Debug or Release build.
4. Build.
To Run on Windows
1. Start a command shell window
2. Add ICU's bin directory to the path, e.g.
set PATH=c:\icu\bin;%PATH%
(Use the path to where ever ICU is on your system.)
3. cd into the uciter8 directory, e.g.
cd c:\icu\source\samples\uciter8\debug
4. Run it
uciter8
To Build on Unixes
1. Build ICU.
Specify an ICU install directory when running configure,
using the --prefix option. The steps to build ICU will look something
like this:
cd <icu directory>/source
runConfigureICU <platform-name> --prefix <icu install directory> [other options]
gmake all
2. Install ICU,
gmake install
3. Compile
cd <icu directory>/source/samples/uciter8
gmake ICU_PREFIX=<icu install directory)
To Run on Unixes
cd <icu directory>/source/samples/uciter8
gmake ICU_PREFIX=<icu install directory> check
-or-
export LD_LIBRARY_PATH=<icu install directory>/lib:.:$LD_LIBRARY_PATH
uciter8
Note: The name of the LD_LIBRARY_PATH variable is different on some systems.
If in doubt, run the sample using "gmake check", and note the name of
the variable that is used there. LD_LIBRARY_PATH is the correct name
for Linux and Solaris.
