       [Common Error] LaTeX Error: Unicode character

       This is about a common error with the message in the subject.
       This could occur when you directly copy and paste sentences from
       a pdf file.
       Sometimes, it can bring incompatible unicode characters into
       your R Markdown document.
       For example, the following error message
       [center]
       --- Quote ---
       > ! LaTeX Error: Unicode character − (U+2212)
       > not set up for use with LaTeX.
       --- End Quote ---
       [/center]
       means the unicode - causes an error.
       (It looks like the hyphen in your keyboard, but actually it is
       different.)
       To fix the issue, you can simple retype the problematic
       character
       so that you can replace the unicode to usual character in your
       keyboard.
       Frequently observed unicode would be -, _, ", ~, etc.
