Character Entities

Character Entities
As with any syntactic language, WML has certain characters that have special meaning. The two most
obvious of these characters are the < and > symbols, which surround all tags. These characters cannot be
typed in directly if the designer's intent is to display these characters. Thus, all characters that can be
displayed in a web browser have numeric values assigned to them. The numeric values are entered into
the source web page as &#nnn; where nnn is a three-digit value. For example, the < symbol is entered as
'&#060;'.
In addition, many of these characters also have names assigned. Name values are entered into the source
web page as &name; where name is the WML name associated with this character. For example, the <
symbol would be entered as '&lt;'. The set of characters defined by the World Wide Web Consortium are
fully supported in the 4620 browser in conformance with the standard.
For convenience, a few of these key symbols are specified below.

Colors and Fonts

The browser supports a 4-grayscale display. Because of the size of the screen on the 4620 IP Telephone,
the browser has only a single font available for use, which is based on Latin-1. Only a normal font weight
is supported. Bold, italic and different font sizes are not supported. The font used by the 4620 defines
characters to have at most six pixels in width.

Wireless Telephony Applications (WTA)

Wireless Telephony Applications (WTA) are those applications designed to interact with the telephony-
related functions present in a phone. The web browser supports:
•
Originating a call - Click to Dial
•
Adding entries to the phonebook (Add to Speed Dial entries)
The Web Browser supports the WTA application "click to dial" any link on the screen. An icon of a
telephone handset is displayed to the left of a "click to dial" link when the link is initially displayed.
The Add to Phonebook WTAI function "wtai://wp/ap;" is used to add a Name and Number to the 4620
Speed Dial application. A Speed Dial icon will be displayed to the left of an "add to phonebook". The
wtai syntax is supported as a href attribute and as such any tags that support the href attribute will be able
