Embedding special characters only makes it harder to remember correctly yet has little benefit. Your example is the same used in the xkcd where they explain this (except you've added an additional word at the beginning) so you've probably seen it already but I'll link it anyways. https://xkcd.com/936/
At work I constantly deal with people who can't remember passwords as short as 8 characters, you have to remember we're not representative of the average person.
