*) When creating WML applications, it is recommended that you
always save the page contents as UTF8, and that this is clearly indi-
cated in the pages before publishing. This ensures that the contents
of the application can be viewed, regardless of character sets used in
gateways and the phone. All characters are not supported in all
phones. The software version depends on which market the phone is
associated to. Also, please note that the phone may not support input
on a WAP Service which uses certain characters (languages), even if
those characters are supported for browsing in the phone.
