Utilities to transcode a integer from and to base 10 to a alphanumerical base where the handwritten numbers won't have potential homoglyphes. It was first developed in a defunct service called “dAgence” as base 33 for generating command references, hence the “base ref” name. It is actually a base 28.
This project is just an exercice (TDD and implementation in numerous languages), but you can use it and fork it. A work-in-progress (french written) post will be published during autumn 2014.
But if you find it really useful, I'll be happy.

Blogged about it there (in French):
The “conventionnal” base 36 uses numbers then letters : 0123456789ABCDEFHIJKLMNOPQRSTUVWXYZ
I'm removing any letter that may be confused with numbers when (badly) handwritten :BGILOSYZ
We have 28 available glyphes : 0123456789ACDEFHJKMNPQRTUVWX

- Coding rules are : TDD, DRY, safe
- Is it possible to do TDD in various languages with only one specification file ?
- Do tests suite have different behaviours ?
- What language is smartest to read afterwards ?
- Ok, it's OOP, but have we smartests patterns ?
- How Json is decoded ?
The class should implements :
isValid(string)- true : if a string has the glyphes even lowercase or a empty string
- false : elsewhere
encode(absolute integer)- string : the translated string
- false : if not an absolute integer, like real or negative numbers or NaN
decode(string)- integer : the transcoded number
- false : if not translatable
It may have an
exceptionfor debug purposes
