Method GetIterAtByte

src/core/utf8.cpp:83–92

* Create iterator pointing at codepoint, which occupies the byte position "offset". * "offset" does not need to point at the first byte of the UTF-8 sequence, * the iterator will still address the correct position of the first byte. * @param offset Byte offset into view. * @return Iterator pointing at start of codepoint, of which "offset" is part of. */

 * @return Iterator pointing at start of codepoint, of which "offset" is part of.
