Re: [HACKERS] utf-8 safe ascii() function

Dear Patrice,

Thank you very much. This will save the lives of Java users.

Yes, this would save the lives of some Javascript users. Java Unicode notation
is the only Unicode understood by Javascript.

Java Unicode notation is not case sensitive ('\u' = '\U') and is followed by
an hexadecimal value.

This would be perfect. We should also handle the HTML unicode nation :
&#{dec_digits} and &#x{hex_digits} as it is unambiguous.
