Introduces intl_convert_utf8_to_utf16_zstr() to convert a UTF-8 string to a UTF-16 string zend_string* instance. This way we avoid a double copy later from a UChar* into a zend_string*.

is that for perf ? avoid copy vs having to calculate buffer before hand it seems. |
Yes
No. The existing code already had to calculate the buffer size beforehand (the call sites passed NULL to the target pointer). |

ah my bad I missed the first call :) ok nice handy helper you made |
