ascii85

Ascii85, also called Base85, is a form of binary-to-text encoding developed by Paul E. Rutter for the “btoa” utility. By using five ASCII characters to represent four bytes of binary data (making the encoded size ¹⁄₄ larger than the original, assuming eight bits per ASCII character), it is more efficient than uuencode or Base64, which use four characters to represent three bytes of data (¹⁄₃ increase, assuming eight bits per ASCII character).

EncConv

EncConv is a package which gives unit EncConv, to convert text to/from UTF8. It was based on LazUtils' unit LConvEncoding , but API was changed and simplified. The list of supported encodings is the same as in LConvEncoding.
