I'm not following the thread, but I'd like to lend full support to the above statement.
base 2^n, 10, 16, 32, 58, 64, 85, 2048:
https://github.com/libbitcoin/libbitcoin-system/tree/master/src/radix
https://github.com/libbitcoin/libbitcoin-system/tree/master/include/bitcoin/system/impl/radix
specifically base_2048:
https://github.com/libbitcoin/libbitcoin-system/blob/master/src/radix/base_2048.cpp
base_2048 encodings with checksum applied:
https://github.com/libbitcoin/libbitcoin-system/tree/master/src/wallet/mnemonics
specifically bip39:
https://github.com/libbitcoin/libbitcoin-system/blob/master/src/wallet/mnemonics/mnemonic.cpp
