Although the input string may contain encoded binary data, the resulting output is treated as a string. As such, any NUL characters in the string will appear as a truncated result.
Padding is optional, and may be omitted. Decoding stops at the first
instance of a

This is the only difference to the
for handling invalid characters and the behavior of padding.
