I´m not worried as it´s the mirror. Hard to panic really when you´re in sunny Tenerife with a glorious view out of the window! Weather still **** in the UK¿ Stupid spanish keyboard only has an upside down question mark!
If you're desperate to get your post correct, just pop off to Google and type 'question mark symbol'. You'll find that Wikipedia has a whole page devoted to typography. Just copy and paste what you need. Otherwise, there is knowing the ASCII or Unicodes off by heart, but I doubt anyone knows those without looking them up.
