save the page contents as UTF-8, and that this is clearly indicated in
the pages before publishing. This ensures that the contents of the
application can be viewed, regardless of character sets used in gate-
ways and the phone. All characters are not supported in all phones.
The software version depends on which market the phone is associ-
ated 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.
