I see it often in material that was composed in some format that had the
equivalent of  and then copied to plain text.

Dad (who teaches physics) says students are increasingly writing "1e4"
rather than "10⁴" -- a good thing, in my opinion, since the
"10" is the least meaningful part of the symbol but the superscript is
customarily written smaller!
