Perhaps; or maybe -std=c++98 would be more appropriate for C++ sources. 
I haven't looked into this in any detail, I'm just aware that a number 
of projects have recently reported issues that arise because ICU's UChar 
typedef changed from uint16_t to char16_t when it's built with a C++11 
compiler. This can cause problems for code that has its own Unicode 
character type based on unsigned short or uint16_t, and expects it to be 
compatible with ICU's UChar. The types themselves interoperate fine, but 
pointers to them are not considered compatible, AIUI.

Another solution (assuming this is the problem people are having) would 
be a sprinkling of explicit (UChar*) typecasts wherever such ICU APIs 
are used with external (unsigned short *) data types.
