Hmm, in Python3, I get: >>> s = "абв.txt" >>> s 'абв.txt' > So one sees that we have hex numbers here. > Same is for typing in the strings which obviously also uses hex. > Same is for some parts of the Python documentation, > especially those about unicode strings. > > PROPOSAL: > 1.

The hex notation for \uXXXX is a standard also used in many other programming languages, it's also easier to parse, so I don't think we should change this default. Take e.g. >>> s = "\u123456" >>> s 'ሴ56' With decimal notation, it's not clear where to end parsing the digit notation. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Experts (#1, Oct 12 2016) >>> Python Projects, Coaching and Consulting ... http://www.egenix.com/ >>> Python Database Interfaces ... http://products.egenix.com/ >>> Plone/Zope Database Interfaces ... http://zope.egenix.com/ ________________________________________________________________________ ::: We implement business ideas - efficiently in both time and costs ::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
