I can use the Windows‑1252 character set for all my writing ... ☺
I find it ironic that you claim to be able to get by with only the Windows‑1252 character set and then a few paragraphs later you use a character that's not in it. Sure you can enter that character using the HTML numeric character entity form ☺ - but then the same is true of any non-ASCII character. So I don't really see why 1252 is so appealing to you. Given the more obvious choices of ASCII or Unicode why choose an encoding that is neither one thing nor the other?
