      5 uciter8: Lenient reading of 8-bit Unicode with a UCharIterator
      6 
      7 This sample demonstrates reading
      8 8-bit Unicode text leniently, accepting a mix of UTF-8 and CESU-8
      9 and also accepting single surrogates.
     10 UTF-8-style macros are defined as well as a UCharIterator.
     11 The macros are incomplete (do not assemble code points from pairs of surrogates)
     12 but sufficient for the iterator.
     13 
     14 If you wish to use the lenient-UTF/CESU-8 UCharIterator in a context outside of
     15 this sample, then copy the uit_len8.c file,
     16 as well as either the uit_len8.h header or just the prototype that it contains.
     17 
     18 *** Warning: ***
     19 This UCharIterator reads an arbitrary mix of UTF-8 and CESU-8 text.
     20 It does not conform to any one Unicode charset specification,
     21 and its use may lead to security risks.

     31 To Build uciter8 on Windows
     32     1.  Install and build ICU
     33     2.  In MSVC, open the workspace file icu\samples\uciter8\uciter8.sln
     34     3.  Choose a Debug or Release build.
     35     4.  Build.
     36 
     37 To Run on Windows
     38     1.  Start a command shell window
     39     2.  Add ICU's bin directory to the path, e.g.
     40             set PATH=c:\icu\bin;%PATH%
     41         (Use the path to where ever ICU is on your system.)
     42     3.  cd into the uciter8 directory, e.g.
     43             cd c:\icu\source\samples\uciter8\debug
     44     4.  Run it
     45             uciter8
     46 
     47 To Build on Unixes
     48     1.  Build ICU.  
     49         Specify an ICU install directory when running configure,
     50         using the --prefix option.  The steps to build ICU will look something
     51         like this:
     52            cd <icu directory>/source
     53            runConfigureICU <platform-name> --prefix <icu install directory> [other options]
     54            gmake all
     55 
     56     2.  Install ICU, 
     57            gmake install
     58 
     59     3.  Compile
     60            cd <icu directory>/source/samples/uciter8
     61            gmake ICU_PREFIX=<icu install directory)
     62 
     63 To Run on Unixes
     64            cd <icu directory>/source/samples/uciter8
     65            
     66            gmake ICU_PREFIX=<icu install directory>  check
     67                -or- 
     68 
     69            export LD_LIBRARY_PATH=<icu install directory>/lib:.:$LD_LIBRARY_PATH
     70            uciter8
     71 
     72 
     73  Note:  The name of the LD_LIBRARY_PATH variable is different on some systems.
     74         If in doubt, run the sample using "gmake check", and note the name of
     75         the variable that is used there.  LD_LIBRARY_PATH is the correct name
     76         for Linux and Solaris.
