How do I use UTF-8? (Read 1067 times)

qilbert YaBB Newbies Offline Posts: 3	How do I use UTF-8? Jan 30^th, 2006, 3:11am Hi I'm doing a processing application and I never manage to get non ascii characters on the input. the example: Examples/Data/CharacterStrings/ will not print the üûä characers for me, when I press them on my keyboard. Anyone knows how to accept 8bit data?

Ok I have tested some more and I would really like some feedback, because sometimes I get the the unicode values for åäö but not always like something like every tenth time.

I've replaced the keyPressed original code with this:

void keyPressed()
{
letter = char(key);
float scale = 100.0/57.0;
int temp = int((key - 'A') * scale);
xoffset = temp;
println("Unicode?: "+ key);
}

Reply #2 - Feb 18^th, 2006, 9:33pm key should always be a unicode char, or the constant CODED if it's a coded key (like when you hit CTRL or OPTION or ALT). the scale/temp/xoffset stuff is gonna be weird because the unicode values can be way out of range, and subtracting 'A' from the value doesn't make much sense with unicode values.

Can you confirm that you get that unicode chars from Processing because I'm not getting any..

Code:


 void keyPressed()
{
    letter = char(key);
    println("Unicode?: "+ key " char:"+ letter +"end");
 }
