One option is to use sorted's key parameter with an appropriate
mapping in a dictionary:

>>> cs = (' ', '.', '\'', '-', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'A', 'ä', 'Ä', 'á', 'Á', 'â', 'Â', 'à', 'À', 'å', 'Å', 'b', 'B', 'c', 'C', 'ç', 'Ç', 'd', 'D', 'e', 'E', 'ë', 'Ë', 'é', 'É', 'ê', 'Ê', 'è', 'È', 'f', 'F', 'g', 'G', 'h', 'H', 'i', 'I', 'ï', 'Ï', 'í', 'Í', 'î', 'Î', 'ì', 'Ì', 'j', 'J', 'k', 'K', 'l', 'L', 'm', 'M', 'n', 'ñ', 'N', 'Ñ', 'o', 'O', 'ö', 'Ö', 'ó', 'Ó', 'ô', 'Ô', 'ò', 'Ò', 'ø', 'Ø', 'p', 'P', 'q', 'Q', 'r', 'R', 's', 'S', 't', 'T', 'u', 'U', 'ü', 'Ü', 'ú', 'Ú', 'û', 'Û', 'ù', 'Ù', 'v', 'V', 'w', 'W', 'x', 'X', 'y', 'Y', 'z', 'Z')

>>> d = { k: v for v, k in enumerate(cs) }

>>> import random

>>> ''.join(sorted(random.sample(cs, 20), key=d.get))
'5aAàÀåBCçËÉíÎLÖøquùx'
