Let's assume for the moment that you're right and that it's not fixable. (I have no reason to doubt you, but, as an optimist, I hold out hope.) Do we at least know which accents and diacriticals won't work, so that we can develop a coherent workaround strategy?

As an aside, I don't think it's weird at all that things are working well on Polish wikis, since a lot of the dev team is Polish. And this is why I hold out hope that there's a solution to this. If language-specific letters like ł can show up, there's no particular logical reason why other language-specific letters, like â, should not be able to show up.
