Lightweight web font customization integrated with glyph demanding assessment

A system for reducing latency associated with downloading web fonts, the system comprising:

• at least one processor;
• and
• at least one memory storing computer-executable instructions, wherein the at least one processor is configured to access the at least one memory and execute the computer-executable instructions to:
• identifying at least one web font associated with a web page being accessed by a client device;
• determining a set of characters contained in web content of the web page;
• extracting, from the identified web font, a set of glyphs corresponding to the set of characters;
• generating a customized lightweight web font containing only the set of glyphs corresponding to only the set of set of characters contained in the web content of the web page;
• validating that the customized lightweight web font can be loaded on the client device;
• providing the customized lightweight web font to the client device to enable rendering of the web content on the client device using the customized lightweight web font, and
• upon identifying at least another web font associated with the web page being accessed by the client device, repeating the method for the at least another web font,
• wherein the at least one processor is configured to determine the set of characters by executing the computer-executable instructions to dynamically scan the web content to identify the set of characters in response to a web font request from the client device, and
• wherein validating the customized lightweight web font comprises determining at least one of whether the client device has sufficient bandwidth to download the customized lightweight web font, and whether the customized lightweight web font can be loaded and utilized by a web browser executing on the client device.

A computer program product for reducing latency associated with downloading web fonts, the computer program product comprising a storage medium readable by a processing circuit, the storage medium storing instructions executable by the processing circuit to cause a method to be performed, the method comprising:

• Identifying at least one web font associated with a web page being accessed by a client device;
• determining a set of characters contained in web content of the web page;
• extracting, from the identified web font, a set of glyphs corresponding to the set of characters;
• generating a customized lightweight web font containing only the set of glyphs corresponding to only the set of set of characters contained in the web content of the web page;
• validating that the customized lightweight web font can be loaded on the client device;
• providing the customized lightweight web font to the client device to enable rendering of the web content on the client device using the customized lightweight web font, and
• upon identifying at least another web font associated with the web page being accessed by the client device, repeating the method for the at least another web font,
• wherein determining the set of characters comprises dynamically scanning the web content to identify the set of characters in response to a web font request from the client device, and
• wherein validating the customized lightweight web font comprises determining at least one of whether the client device has sufficient bandwidth to download the customized lightweight web font, and whether the customized lightweight web font can be loaded and utilized by a web browser executing on the client device.

A computer-implemented method for performing a glyph demanding assessment of web content, the method comprising:

• scanning the web content to identify a set of characters contained in the web content;
• determining a set of attributes associated with the web content, the attributes including a web font identifier corresponding to a web font to be used to render the web content;
• populating a data structure with the set of attributes;
• iteratively populating the data structure with each identified character contained in the web content;
• and
• generating a customized lightweight web font containing only the set of glyphs corresponding to only the set of set of characters contained in the web content, and
• upon receiving a web font request from a client device, retrieving the customized lightweight web font, and validating that the customized lightweight web font can be loaded on the client device prior to providing the customized lightweight web font to the client device,
• wherein the web content is scanned statically and the data structure is populated prior to receipt of a request for a web page containing the web content and the attributes,
• wherein the customized lightweight web font is stored in a web font repository and is associated with the web font identifier corresponding to the web font used to render the web content, and
• wherein validating the customized lightweight web font comprises determining at least one of whether the client device has sufficient bandwidth to download the customized lightweight web font, and whether the customized lightweight web font can be loaded and utilized by a web browser executing on the client device.
