Sure, you can, just tell us which browser you use. If you use chrome or a Chromiun derivative you can use Use My Words If you are using Firefox you can use FoxReplace And if you are using Edge/IE then use a real browser please.
you should be able to if you use a different font? btw what is that? is that actually a "!?" ??? never seen it... I thought it was a letter
I don't think that would work, since that's a single character and not a ligature of two characters (two characters combined into a single glyph). If anything using a different font may just make that disappear completely. Using a find and replace tool would work better. BTW, the unicode character ⁉ is similar, as it's a single character depicting two symbols. PS: If you are a translator please don't use full-width question or exclamation marks, sometimes they don't render properly, and even if they do render properly they just look like a mistake when there's a space between the end of the word and the mark. Question? Question? Exclamation! Exclamation!
it's true. I didn't know what it was, apparently it is called interrobang... replacing it would be better... but if the text is really long or getting loaded with ajax like it's done in a certain qi site, it might not work well.
You could replace that glyph with a single '?'. You might lose the impact of the interrobang, but you'll retain the grammatical structure of the interrogative.
Never used them, so I can't say for sure. There are a lot of different ways for websites to render in your browser, so it might not work everywhere.
While I haven't used the chrome extension I have used FoxReplace or one quite similar to it. While it may not imminently replace words in pages that use infinite scrolling it does have a way to apply changes to the currently rendered page. It basically look at anything that isn't an HTML tag, and if you tell it even them, and makes the changes. So even in a page like that Q site it should work perfectly.
