Writing to the console using fprintf of std:: is possible. I usually
output on the error stream for the debugging purposes.

The problem here is to get a C string from them: here are some examples:
 * from OUString:
    rtl::OUStringToOString( sOUStr, RTL_TEXTENCODING_UTF8 ).getStr()

 * from String / UniString
    ByteString( sToolStr, RTL_TEXTENCODING_UTF8 ).GetBufferAccess()

I typed those without checking the case... I hope it's OK, otherwise,
just check the code for the correct syntax.
