示例1: saveConvert
/*
* Converts unicodes to encoded \uxxxx and writes out any of the
* characters in specialSaveChars with a preceding slash
*
* @param theString
* the string needing convert.
* @param dst
* Save of the result
* @param offset
* the offset of result
* @param escapeSpace
* if <code>true</code>, escape Space
* @param lengthFlag
* Whether add one byte of length in the result.
* <code>true</code> add one byte of length in the result
* @param getLengthFlag
* Calculate the length of result, if <code>true</code>, thestring length that return.
* @return if getLengthFlag = false, return offset of the result.
* if getLengthFlag = true, the length of the sequence of characters represented by this
* object.
