nbaser
Library allowing for consistent and reversible encode/decode operations between arbitrary unicode character bases. Supports bases from 2 to 256.
Install
$ nimble install nbaser
import in your project and use
import nbaser
const bs58 = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"
echo bs58.decode("1Q2TWHE3GMdB6BZKafqwxXtWAWgFt5Jvm3")

Notes
This library does not support padding, such as that found in "standard" base32 and base64.
It utilizes the leading zero compression found in base58, thereby supports it and its variants, and does not require padding.
Due to the unicode support, there is quite some performance overhead relatively to just supporting ASCII. It results in up to an order of magnitude slowdown, but should still be fast enough. Check benchmarks.
