[Foundation] Writes the given
range of characters into
buffer in a given
encoding, without any allocations. Does not NULL-terminate.
buffer: A buffer into which to store the bytes from
the receiver. The returned bytes are not NUL-terminated.
maxBufferCount: The maximum number of bytes to write
usedBufferCount: The number of bytes used from
nil if you do not need this value.
encoding: The encoding to use for the returned bytes.
options: A mask to specify options to use for
converting the receiver’s contents to
encoding (if conversion
range: The range of characters in the receiver to get.
leftover: The remaining range. Pass
nil If you do
not need this value.
true iff some characters were converted.
Note: Conversion stops when the buffer fills or when the
conversion isn't possible due to the chosen encoding.
Note: will get a maximum of
min(buffer.count, maxLength) bytes.
