示例1: prepare
/**
* Prepare the input buffer for use in applications with the given profile. This operation maps, normalizes(NFKC),
* checks for prohited and BiDi characters in the order defined by RFC 3454
* depending on the options specified in the profile.
*
* @param src A UCharacterIterator object containing the source string
* @param options A bit set of options:
*
* - StringPrep.NONE Prohibit processing of unassigned code points in the input
*
* - StringPrep.ALLOW_UNASSIGNED Treat the unassigned code points are in the input
* as normal Unicode code points.
*
* @return StringBuffer A StringBuffer containing the output
* @throws ParseException
* @draft ICU 2.8
