Abstract: A device may be configured to enable a user to select a language, and may fulfill resource requests from applications by selecting, from among resources respectively associated with a language, a resource associated with the selected language of the user. However, this resource selection process may be inadequate if the user selects multiple languages; if a resource associated with the selected language of the user is unavailable, but resources associated with related languages are available; or if the user and/or the application specifies an ordering for the selection among the languages. Presented herein are techniques for performing the resource selection by, for respective languages selected by the user, calculating a weight representing a suitability of the language for the resource request; generating a selection order of the selected languages according to the weights; and selecting a resource based on the position of the associated language in the selection order.

Abstract: Conditional determination of glyph substitution (GSUB) lookups or glyph positioning (GPOS) lookups in the process of rendering a string of text as a sequence of glyphs is described. A process can include receiving a string of text comprising a sequence of characters, obtaining a sequence of glyph identifiers (IDs) corresponding to the sequence of characters, and determining that a context of the string of text satisfies a condition. Based at least in part on the context satisfying the condition, an alternate lookup can be determined and executed in lieu of a default lookup. Execution of the alternate lookup causes a GSUB operation or a GPOS operation to be performed on the sequence of glyph IDs to ultimately cause the string of text to be rendered on a display as a sequence of glyphs with a typographical feature applied thereto.

Abstract: Language selection and application within a computing environment are often distributed over and differently applied by the operating system and various applications, leading to additional administration, inconsistencies in the user experience based on different language feature implementations among different applications; and increased cost and redundancy in developing language features for different applications. Presented herein are techniques for configuring a device with an application language library that centralizes the selection of languages by the user, and that provides a wide variety of language features (e.g., text translation, user interface adaptation, and data formats) to the applications and operating system.
