Completing typeset characters using handwritten strokes

A computing device for performing character completion in a text of a digital document, comprising:

• a display interface configured to display at least one typeset character of the text;
• an input surface configured to detect a handwritten input stroke input on the digital document, in the vicinity of a first typeset character of said at least one typeset character;
• an identification module configured to check whether the first typeset character is part of a predefined list of base characters according to a language model, and configured to identify the first typeset character as a base character capable of character completion if the first typeset character belongs to the predefined list;
• a retrieving module configured to retrieve from pre-stored data, from a first memory, a predefined character version of the first typeset character different from the first typeset character;
• a generation module configured to generate a hybrid character by replacing the first typeset character by the predefined character version, said hybrid character being formed by a combination of the predefined character version and the handwritten input stroke;
• a recognition module configured to perform a character recognition on the hybrid character to generate a list of at least one character candidate with associated probabilities of recognition of the hybrid character;
• and
• a language module configured to select a recognized combined character from the character candidate list based on the associated probabilities.
