示例1: ConvertString
void FStringConverter::ConvertString(const TCHAR* Source, const int32 SourceStartIndex, const int32 SourceLen, icu::UnicodeString& Destination, const bool ShouldNullTerminate)
{
if (SourceLen > 0)
{
UErrorCode ICUStatus = U_ZERO_ERROR;
ucnv_reset(ICUConverter);
// Get the internal buffer of the string, we're going to use it as scratch space
const int32_t DestinationCapacityUChars = SourceLen * 2;
UChar* InternalStringBuffer = Destination.getBuffer(DestinationCapacityUChars);
// Perform the conversion into the string buffer
const int32_t SourceSizeBytes = SourceLen * sizeof(TCHAR);
const int32_t DestinationLength = ucnv_toUChars(ICUConverter, InternalStringBuffer, DestinationCapacityUChars, reinterpret_cast<const char*>(Source + SourceStartIndex), SourceSizeBytes, &ICUStatus);
// Optionally null terminate the string
if (ShouldNullTerminate)
{
InternalStringBuffer[DestinationLength] = 0;
}
// Size it back down to the correct size and release our lock on the string buffer
Destination.releaseBuffer(DestinationLength);
check(U_SUCCESS(ICUStatus));
}
else
{
Destination.remove();
}
}示例2: ustring_from_char
bool ustring_from_char(icu::UnicodeString& ret,
const String& str,
UErrorCode &error) {
int32_t capacity = str.size() + 1;
UChar *utf16 = ret.getBuffer(capacity);
int32_t utf16_len = 0;
error = U_ZERO_ERROR;

str.c_str(), str.size(),
U_SENTINEL /* no substitution */,
nullptr, &error);
ret.releaseBuffer(utf16_len);
if (U_FAILURE(error)) {
ret.setToBogus();
return false;
}
return true;
}示例3: U_SUCCESS
static int

return -1;
} else {
// Returns FALSE=0 for U_STRINGPREP_UNASSIGNED_ERROR and processing errors,
// TRUE=1 if c is valid or mapped.
return U_SUCCESS(errorCode);
}
