for
Ascii85/base85 encoding.
This module is browser compatible.
Specifying a standard and delimiter
By default, all functions are using the most popular Adobe version of ascii85
and not adding any delimiter. However, there are three more standards
supported - btoa (different delimiter and additional compression of 4 bytes
equal to 32), Z85 and
RFC 1924. It's possible to use a
different encoding by specifying it in options
object as a second parameter.
Similarly, it's possible to make encode
add a delimiter (<~
and ~>
for
Adobe, xbtoa Begin
and xbtoa End
with newlines between the delimiters and
encoded data for btoa. Checksums for btoa are not supported. Delimiters are not
supported by other encodings.)
