Abstract: A system and method for displaying complex scripts with a cloud computing architecture may include a client device and a cloud computing server. The client device accesses a web application via the internet and transmits a request containing complex scripts to the cloud computing server. The cloud computing server parses the text and breaks the text down to a sequence of characters of a particular script, and maps the Unicode of each character to a particular glyph to obtain a glyph ID for each character making a one to one relationship. The cloud computing server analyzes each character, assigns, and applies specific font related operations to each glyph. The cloud computing server optimizes and compresses the glyph ID and positioning data, and transmit the compressed data back to the client device to be rendered on the display of the client device.
