Abstract

When a browsing computer navigates to a network document, such as a web page, the corresponding server also downloads computer readable formatting information necessary for the operating system of the browsing computer to render correctly any characters within the network document even if the fonts associated with those characters do not exist on the browsing computer prior to encountering the network document. An exposure module is also downloaded to the browsing computer. The exposure module is loaded onto the browsing computer, which in turn either permanently installs or temporarily exposes the operating system of the browsing computer to the computer readable font formatting information associated with the network document. As a result, the operating system of the browsing computer is able to display or otherwise process the network document correctly and consistently regardless of the computer readable fonts installed on the browsing computer.

a font package comprising one or more external font files that include formatting information necessary for the hand-held device to render the at least one of the plurality of display characters using the one or more identified external fonts, the font package separate from the computer executable instructions for identifying the plurality of display characters for display; and

an exposure module for installation of the one or more external font files in a temporary fonts directory on the hand-held device, the one or more external font files being received from the computer responsive to the computer receiving a request for the font package from the hand-held device so that the hand-held device can render the at least one of the plurality of display characters using the one or more external font files, whereby when the plurality of display characters are displayed, the plurality of display characters are displayed by a program module of the operating system using the one or more external font files, wherein in response to the one or more external font files being installed, a system font table of the hand-held device is updated to reflect an availability of the external font files.

2. The non-transitory computer-readable medium as recited in claim 1, wherein the electronic file package further includes the font package.

3. The non-transitory computer-readable medium as recited in claim 1, wherein the font package comprises computer readable formatting information necessary for the hand-held device to render one or more display characters that are non-standard display characters using one or more identified fonts that are non-standard fonts.

4. The non-transitory computer-readable medium as recited in claim 1, wherein the font package further comprises handling information that enables an operating system of the hand-held device to selectively manipulate the plurality of display characters in ways not included in a default handling of characters by the operating system of the hand-held device for lack of non-standard fonts.

5. The non-transitory computer-readable medium as recited in claim 1, wherein:

the exposure module comprises computer executable instructions for automatic installation or exposure of the font package; and

the computer executable instructions for installation or exposure of the font package comprises computer executable instructions for saving font rendering information of the font package to an internal memory of the hand-held device, a hidden temporary file, or a virtual memory mapped file.

6. A computer-implemented method, comprising:

requesting, by a hand-held device with an operating system that recognizes a standard set of fonts, a network document that is hosted on a server communicatively coupled to the hand-held device via a network, the network document including;

an application file comprising computer executable instructions identifying a plurality of display characters used in the network document, and

computer executable instructions identifying a font used to render at least one display character of the plurality of display characters, the font not being included in the standard set of fonts;

accessing the network document;

receiving, at the hand-held device, a font package separate from the application file of the network document and referenced by the computer executable instructions of the network document, the font package comprising computer readable formatting information for the operating system of the hand-held device to render the at least one display character using the font and for other applications controlled by the operating system of the hand-held device to render the at least one display character using the font; and

responsive to the hand-held device accessing the network document;

installing the computer readable formatting information of the font package in a temporary fonts directory on the hand-held device so as to enable a program module of the operating system of the hand-held device to render the at least one display character using the font, wherein when the at least one display character is displayed, the at least one display character is displayed using the computer readable formatting information installed in the temporary fonts directory, and

updating a system font table of the hand-held device to reflect an availability of the font.

7. The computer-implemented method of claim 6, further comprising, rendering the at least one display character using the font on a display of the hand-held device.

8. The computer-implemented method of claim 7, wherein the network document comprises a plurality of application files including the application file and a plurality of font packages including the font package.

9. The computer-implemented method of claim 7, wherein the computer readable formatting information comprises scalable outlining formatting information.

10. The computer-implemented method of claim 9, further comprising after receiving the font package and prior to rendering the at least one display character using the font on the display of the hand-held device, disconnecting from the network and remaining disconnected from the network until after the hand-held device has rendered the at least one display character using the font on the display of the hand-held device.

11. A hand-held device coupleable to a network such that the hand-held device can receive information from a non-transitory computer-readable medium adapted for use with a second computer coupled to the network, the hand-held device comprising:

a display;

a processing unit; and
