15. The media of claim 14 , wherein providing real-time handwriting recognition results to the user further comprises: segmenting the user's handwriting input into one or more recognition units, each recognition unit comprising one or more of the handwritten strokes provided by the user; providing a respective image of each of the one or more recognition units as an input to the multi-script handwriting recognition model; and for at least one of the one or more recognition units, obtaining from the multi-script handwriting recognition model, at least a first output character from a first script, and at least a second output character from a second script different from the first script.
14. A non-transitory computer-readable media having instructions stored thereon, the instructions, when executed by one or more processors, cause the processors to perform operations comprising: receiving a multi-script handwriting recognition model, the multi-script recognition model having been trained on spatially-derived features of a multi-script training corpus, the multi-script training corpus including respective handwriting samples corresponding to characters of one or more scripts; receiving a handwriting input from a user, the handwriting input comprising a plurality of handwritten strokes corresponding to a plurality of scripts provided on a touch-sensitive surface coupled to a user device; and in response to receiving the handwriting input comprising a plurality of handwritten strokes corresponding to a plurality of scripts, providing in real-time one or more handwriting recognition results to the user based on the multi-script handwriting recognition model that has been trained on the spatially-derived features of the multi-script training corpus, wherein the one or more handwriting recognition results includes characters from a plurality of scripts.
