Google hasn't been a help.

A quick search on Google for "unicode for upside down question mark" led me to a Wikipedia article, which stated that

The inverted question mark (¿) corresponds to Unicode code-point 191 (U+00BF)

¿ɹoɟ buıʞooן ǝɹǝʍ noʎ ʇɐɥʍ ʇɐɥʇ sı

Did you write that in Unicode?

@dmindreader: Um.. Probably. I just did a Google search for "flip text", found http://www.fliptext.org/ and copy-pasted the result from there :)

If you want to obtain the Unicode value of a character you can use this simple Javascript :

javascript:alert("¿".charCodeAt(0))

This will alert the Unicode value of the character. If you want to use it in HTML, the synthax is & #191; (without space between & and #) where 191 is the Unicode number of your character.

+1 nice trick (II)!

...and if you want the U+nnnn hex code unit, `'¿'.charCodeAt(0).toString(16)`.

Unicode table might be helpful 00A01F.

Gabriel Ščerbák
It isn't `00a01f`; you add `1f` to `00a0` using hex arithmetic, giving `00bf`.

@Delan Azabani makes sense thanks for explanation!

No problem :) (15 chars)

If you know Java you can print it like this:

$ cat UnicodeTest.java  
public class UnicodeTest { 
    public static void main( String [] args )  { 
        System.out.println( ( int ) '¿' );
    }
}


$ javac -encoding UTF8 UnicodeTest.java  
$ java UnicodeTest
191

Answer 191

Java's characters are unicode.

BTW, ¡That's not an upside down question mark! it is an "opening" question mark. It is just not everyone uses it, just like a '(' is not an upside parenthesis.

The Unicode standard calls it an 'INVERTED QUESTION MARK'

I use this site as search tool for unicode characters. Here are the search results for ¿. It has one result: Unicode Character 'INVERTED QUESTION MARK' (U+00BF).

Useful site.
