Examples of escape forms are "U+4E01" and "". * Escape forms have a prefix and suffix, either of which may be * empty, a radix, typically 16 or 10, a minimum digit count, * typically 1, 4, or 8, and a boolean that specifies whether * supplemental characters are handled as 32-bit code points or as two * 16-bit code units. Most escape forms handle 32-bit code points, * but some, such as the Java form, intentionally break them into two * surrogate pairs, for backward compatibility. * * <p>Some escape forms actually have two different patterns, one for * BMP characters (0..FFFF) and one for supplements (>FFFF). To * handle this, a second EscapeTransliterator may be defined that * specifies the pattern to be produced for supplementals. An example * of a form that requires this is the C form, which uses "\\uFFFF" * for BMP characters and "\\U0010FFFF" for supplementals. * * <p>This class is package private. It registers several standard * variants with the system which are then accessed via their IDs. * * @author Alan Liu */ class EscapeTransliterator : public Transliterator { … }; U_NAMESPACE_END #endif /* #if !UCONFIG_NO_TRANSLITERATION */ #endif
