c++ - ICU, Unicode and libraries -

my goal implement unicode in utf-16 format in embedded system. want able use multiple languages display on lcd. texts in multiple languages going written in separate text files. program eclipse gcc compiler.

i've done research unicode , seems icu holds libraries unicode working on embedded systems. icu version i've downloaded written windows visual studio 10. i'm new program bear me.. i've installed microsoft visual c++ 2010 compile icu , changed library path mentioned in readme file. when trying run cintltst im getting following error:

#### note:  icu init without build-specific setdatadirectory() failed. u_file_access_error #### error! c:\documents\icu\source\test\cintltst\.\x86\debug\cintltst.exe: u_init() failed status = "u_file_access_error". *** check icu_data environment variable , *** check data files present. *** exiting.  use '-w' option if data files *** purposely removed, continue test anyway. 

now couple of questions:

1) don't know file icu expecting, or should expect proper output.

2) need include library of unicode in form?

3) if i'm able run sample program, should change prior copying needed files own software?

4) software shows me failure of check normal when icu data not packaged shared library. mean need package icu data somehow?

i think in settings of visual studio not correct.

thanks time!
