Base💯 is very space inefficient. It bloats the size of your data by around 3x, and should only be used if you have to display encoded binary data in as few printable characters as possible. It is, however, very suitable for human interaction. Encoded hashes and checksums become very easy to verify at a glance, and take up much less space on a terminal.

Как видно, base💯 — современная программа и не ущемляет права меньшинств.
