public class UnicodeUnescaper extends CharSequenceTranslator
Translates escaped Unicode values of the form \\u+\d\d\d\d back to Unicode. It supports multiple 'u' characters and will work with or without the +.
Translate a set of codepoints, represented by an int index into a CharSequence, into another set of codepoints. The number of codepoints consumed must be returned, and the only IOExceptions thrown must be from interacting with the Writer so that the top level API may reliably ignore StringWriter IOExceptions.
- Specified by:
input- CharSequence that is being translated
index- int representing the current point of translation
out- Writer to translate the text to
- int count of codepoints consumed
IOException- if and only if the Writer produces an IOException
