The Unicode character at this iterator is returned. (Equivalent to operator* on a C++ iterator.) If the element at this iterator is a non-character element, such as an image embedded in the buffer, the Unicode “unknown” character 0xFFFC is returned. If invoked on the end iterator, zero is returned; zero is not a valid Unicode character. So you can write a loop which ends when TextIter.getChar returns 0.

class TextIter
