A menu with "我的帳戶" in it, and often a generic icon or no icon at all, doesn't really have sufficient context to determine what the button means. If the website is already translated into your language then great, but many websites aren't (because it's a small site, or you don't speak one of the most common languages, or it's aimed at a different audience, etc.)
Bad UX is the result, from the combination of disabling text selection and being in a language you don't understand. Ideally both would be fixed - since unselectable text causes UX issues even when in a language I understand (when I want to select as I'm reading to keep place, or copy a partial link, or right click -> search/define a technical term, or copy-paste to tell someone what button to click, etc.)
