Support for Japanese number characters in Math Check

3 years 11 months ago #9529 by correns
Hello, you have a great extension there!

It would be even better if it could accept numbers typed from a Japanese keyboard. This would make it the only good captcha I know that works in Japan. So please add this functionality, I really need it for my client, also.

Let me explain how you can do it:

1234567890
1234567890

You see the difference? The first one is Japanese. So when a Japanese person uses your captcha (the math question), and enters the answer in Japanese characters it will produce an error. So the user needs to switch to a western keyboard, but many don't know this. That makes the spam check unusable for now.

BUT, it is easily fixed. This is the UTF representation for 1234567890, understandable by .php etc.:
1234567890


So in the function where you compare the string input with the solution to the mathproblem, just do something like

array(1234567890)
IF (stringinput==mathsolution)OR(stringinput=="array(mathsolution(digit1))&array(mathsolution(digit2))")

and it should work. Sorry for the pseudo code, but you get the idea, right?

Hope you can add this, thank you for your support!
