fun String.encodeToByteArray(
    startIndex: Int, 
    endIndex: Int, 
    throwOnInvalidSequence: Boolean
): ByteArray

Encodes this string or its substring to an array of bytes in UTF-8 encoding.

Parameters

startIndex - the beginning (inclusive) of the substring to encode, 0 by default.

endIndex - the end (exclusive) of the substring to encode, length of this string by default.

throwOnInvalidSequence - specifies whether to throw an exception on malformed char sequence or replace.

Exceptions

IllegalArgumentException - if startIndex is greater than endIndex.

CharacterCodingException - if this string contains malformed char sequence and throwOnInvalidSequence is true.
