Yes, that is an issue, isn't it? 'To' is an inherent part of the infinitive form in English, and yet a completely separate word, which is odd enough in itself, but then to have it be the same word as the preposition! We need excessive homophone police. (This rapidly becomes clear when teaching English as a second language!)

However, as an English teacher, I beg mercy - the last thing we need in yet another spelling of 'to/too/two' tu teach!
