Abstract
Acquisition of a font portion using a compression mechanism is described. In certain embodiments, an end-user device determines multiple characters to be displayed but are missing from a local font. The end-user device computes a compressed representation of the multiple characters based on multiple code points corresponding to the multiple characters. The end-user device transmits a font request including the compressed representation to a font repository. The font request may be implemented as a uniform resource locator (URL). The font repository, such as a server, decodes the compressed representation to identify at least the multiple code points encoded by the end-user device. The font repository prepares a font description including glyph data corresponding to the multiple code points and returns the font description. The end-user device produces a local font that includes at least multiple glyphs corresponding to the multiple requested characters. The local font production may include font augmentation.
