`  == Common misspelling == Because the exclusion of the Umlaut mark is nine times out of ten not intentional, I have changed the beginning text of this article from ``commonly misspelled`` to ``alternately spelled``. This is because of the extreme difficulty involved in inserting the symbol, especially in or on websites or webpages, or any place that the code for the symbol must be used. This is usually not intentional, this is done out of lack of knowledge. Please see the article on misspelling. (By the way, the list of ``famous accidental misspellings`` is pretty interesting).
