Create an INTL_UnicodeToStrIterator and iterate through it once. This function creates an INTL_UnicodeToStrIterator and iterates through it once to get the first element of Unicode text for font encoding conversion. The function uses the prioritized Character Set ID list (CSIDList) to decide which font encoding it will convert to. The iteration stops if the whole Unicode string is converted. Otherwise, it continues iterating and uses the next charset in the CSIDlist to convert the Unicode text.
