the X Window System fonts contained for a long time the following mutually symmetric glyphs
These shapes were even sanctioned by an early US version of the ISO 646 standard (ANSI X3.4, also known as ASCII)
He seems to imply that this practice exists because of a hack in a certain system (similar to Japanese computers replacing the backslash with a Yen symbol) but this isn't the case. The standard goes back to the
original ASCII publication, before the X Window System was even conceived.
Not all characters look exactly how they should, because ASCII only seven bits to work with so characters can have multiple meanings. For example, ' is used as an apostrophe, " is used as a double prime, and - is used as a dash. All have been superseded by dedicated Unicode characters, but for some reason people like to pick on old ASCII quotation marks yet have no problem with these.
