The encoded byte string is returned. foldspaces is an optional flag that uses the special short sequence 'y' instead of 4 consecutive spaces (ASCII 0x20) as supported by 'btoa'. This feature is not supported by the "standard" Adobe encoding. wrapcol controls whether the output should have newline ('\n') characters added to it. If this is non-zero, each output line will be at most this many characters long. pad controls whether the input string is padded to a multiple of 4 before encoding. Note that the btoa implementation always pads. adobe controls whether the encoded byte sequence is framed with <~ and ~>, which is used by the Adobe implementation.
