From 48ff92e300696e2449070ac03b4916c76d4e77a3 Mon Sep 17 00:00:00 2001 From: Arthur de Jong Date: Sun, 28 Apr 2019 23:35:42 +0200 Subject: Use an internal isdigits() function instead of str.isdigit() The problem with the latter is that it will also accept all kinds of unicode digits that are not the ASCII 0-9 digits causing all kinds of problems in check digit calculations. Some of these unicode characters are also considered digits by int() but some are not (such as the SUPERSCRIPT TWO unicode character).
