CamelCase is sometimes used in the writing or translation of certain scripts as a way to tell the difference between ceratin letters or markings. An example is the rendering of Tibetan proper names like "rLobsang": the "r" here stands for a prefix glyph in the original script that functions as tone marker rather than a normal letter. Another example is "tsIurku", a Latin transcription of the Chechen term for the capping stone of the characteristic Medieval defensive towers of Chechenia and Ingushetia; the capital letter "I" here showing a phoneme different from the one transcribed as "i".
