If you type just a minus (-) character in the search box of enwiki and press Enter, it will take you to https://en.wikipedia.org/w/index.php?title=-&redirect=no which in turn redirects you to https://en.wikipedia.org/wiki/Hyphen-minus
But in fawiki, it takes you to https://fa.wikipedia.org/w/index.php?title='&redirect=no which in turn takes you to https://fa.wikipedia.org/wiki/آپاستروف (Apostrophe) which makes no sense.
Why does the - character get interpreted as ' ?
