Convert ICU UnicodeString to platform dependent char * (or std::string)

In my application I use ICU UnicodeString to store my strings. Since I use some libraries incompatible with ICU, I need to convert UnicodeString to its platform dependent representation.

Basicly what I need to do is reverse process form creating new UnicodeString object - new UnicodeString("string encoded in system locale").

I found out this topic - so I know it can be done with use of stringstream.

So my answer is, can it be done in some other simpler way, without using stringstream to convert?

You could use UnicodeString::extract() with a codepage (or a converter). Actually passing NULL for the codepage will use what ICU detected as the default codepage.

You could use the functions in ucnv.h -- namely void ucnv_fromUnicode (UConverter *converter, char **target, const char *targetLimit, const UChar **source, const UChar *sourceLimit, int32_t *offsets, UBool flush, UErrorCode *err). It's not a nice C++ API like UnicodeString, but it will work.

I'd recommend just sticking with the operator<< you're already using if at all possible. It's the standard way to handle lexical conversions (i.e. string to/from integers) in C++ in any case.
