/**
* ICU-internal class CStr, a small helper class to facilitate passing UnicodeStrings
* to functions needing (const char *) strings, such as printf().
*
* It is intended primarily for use in debugging or in tests. Uses platform
* default code page conversion, which will do the best job possible,
* but may be lossy, depending on the platform.
*
* If no other conversion is available, use invariant conversion and substitute
* '?' for non-invariant characters.
*
* Example Usage:
* UnicodeString s = whatever;
* printf("%s", CStr(s)());
*
* The explicit call to the CStr() constructor creates a temporary object.
* Operator () on the temporary object returns a (const char *) pointer.
* The lifetime of the (const char *) data is that of the temporary object,
* which works well when passing it as a parameter to another function, such as printf.
