Is this a known issue? If you type in 
somewhere it will be replaced by 
Don't get me started on how this messes up linux commands and scripts, Is this a me problem or a lemmy problem? I need to study, if this is a known problem, then fine, but if it isn't then it needs to be reported.
What in the gosh darn condescending non sequitur is that? I have a special kind of dislike for people who, instead of trying to promote learning for anyone and everyone at any stage, instead choose to ridicule people for having missed some trivial detail that has about as much in common with Bash as does COBOL (basically nothing). Web scripting is, unsurprisingly, its own skill, and it's very, surpassingly, extremely, stupendously, and obviously conceivable that someone could have years of Bash experience but only recently started putting around with scripting for things like API access or HTML parsing. But you should know this already. :)
Text encoding is SUPER basic and anyone looking to get involved in Linux or scripting absolutely should know that stuff FIRST.

Here's a good primer:

Really, ALL of the W3Schools stuff is just fantastic. Anyone remotely interested in this stuff should start at the beginning there and work up.
