Return the next character to be read without advancing the internal position.
Returns END_OF_READER if there isn't a character to read.

Read a single character and advance the internal position.
Note that the interal position may advance more than one byte for a single character read. Returns END_OF_READER if there isn't a character to read.

Read up to len
characters into buf and advance the internal position accordingly.
Returns the number of characters read into buf. Note that the value returned may be less than the number of bytes that the internal position advances, due to multi-byte characters.
