You should mention that some very common typefaces (fonts) are more confusable than others. For instance, Arial (a common font on Windows systems) makes the two letter combination 'rn' virtually indistinguishable from the single letter 'm'. > >Before the age of computers, most mechanical typewriters lacked the keys > >for the digits ``0`` and ``1`` I'm not sure that "most" is justifed here. One of the most popular typewriters in history, the Underwood #5 (from 1900 to 1920), lacked the 1 key but had a 0 distinct from O. https://i1.wp.com/curiousasacathy.com/wp-content/uploads/2016/04/underwood-no-5-standard-typewriter-circa-1901.jpg The Oliver 5 (1894 – 1928) had both a 0 and a 1, as did the 1895 Ford Typewriter. As did possibly the best selling typewriter in history, the IBM Selectric (introduced in 1961). http://www.technocrazed.com/the-interesting-history-of-evolution-of-typewriters-photo-gallery Perhaps you should say "many older mechanical typewriters"? > >Bidirectional Text > >------------------ The section on bidirectional text is interesting, because reading it in my email client mutt, all the examples are left to right.

Typo: "algorithms". This is a good and useful document, thank you again. -- Steve _______________________________________________ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/CHGK6LLBMVRQ6GGEMRWYJNRLUL7KUMVS/ Code of Conduct: http://python.org/psf/codeofconduct/
