* u_strToPunycode() converts Unicode to Punycode.

* The output will be represented as an array of ASCII code points.

|
|
* The output string is NUL-terminated according to normal ICU
|
|
* string output rules.

|
|
* This function handles a limited amount of code points
|
|
* (the limit is >=64).
|
|
* U_INDEX_OUTOFBOUNDS_ERROR is set if the limit is exceeded.
|
|
* @param srcLength Number of UChars in src, or -1 if NUL-terminated.
|
|
* @param dest Output Punycode array.
|
|
* @param destCapacity Size of dest.
|
|
* @param caseFlags Vector of boolean values, one per input UChar,
|
|
* indicating that the corresponding character is to be
|
|
* marked for the decoder optionally
|
|
* uppercasing (true) or lowercasing (false)
|
|
* the character.
|
|
* ASCII characters are output directly in the case as marked.
|
|
* Flags corresponding to trail surrogates are ignored.
|
|
* If caseFlags==NULL then input characters are not
|
|
* case-mapped.
|
|
* @param pErrorCode ICU in/out error code parameter.
|
|
* U_INVALID_CHAR_FOUND if src contains
|
|
* unmatched single surrogates.
|
|
* U_INDEX_OUTOFBOUNDS_ERROR if src contains
|
|
* too many code points.
|
|
* @return Number of ASCII characters in puny.
