std.encoding needs a complete overhaul. Other encoding packages as std.ascii, std.base64, std.utf8 could be included and a common API should unite them.
This new package could include a comprehensive set of encoder, covering (in addition to base64 and utf8) all the baseXX encoders, since they are easy addition (base16, base32, z85) and also domain specific encoders such as percent encoding (which then could be used in any replacement of the old-fashioned and incomplete std.uri module) or variable length quantity.
For base32, there's already this package in the wild:
