UNISTR_FROM_STRING_EXPLICIT UnicodeString(const char *codepageData)
char* constructor.
UnicodeString(UnicodeString &&src) U_NOEXCEPT

void swap(UnicodeString &other) U_NOEXCEPT
Swap strings.
void toUTF8(ByteSink &sink) const
Convert the UnicodeString to UTF-8 and write the result to a ByteSink.
virtual UClassID getDynamicClassID() const
ICU "poor man's RTTI", returns a UClassID for the actual class.
UnicodeString & operator=(UnicodeString &&src) U_NOEXCEPT
Move assignment operator; might leave src in bogus state.
UnicodeString & toLower(void)
Convert the characters in this to lower case following the conventions of the default locale.

U_EXPORT UBool operator==(const StringPiece &x, const StringPiece &y)
Global operator == for StringPiece.
UBool operator!=(const StringPiece &x, const StringPiece &y)
Global operator != for StringPiece.
const UChar * toUCharPtr(const char16_t *p)
Converts from const char16_t * to const UChar *.
