UTF-8 safe ascii() function

Dear all,

I would like to transform UTF-8 strings into Java-Unicode. Example :
- Latin1 : 'é'
- UTF-8 : 'é'
- Java Unicode = '\u00233'

Basically, a Unicode compatible ascii() function would be fine.
ascii('é') should return 233.

1) Has anyone written an ascii UTF-8 safe wrapper to ascii() function? If yes,
would you be so kind to publish this function on the list.

2) Are there plans to add an ascii() UTF-8 safe function to PostrgeSQL?

Best regards,
Jean-Michel POURE
