(input-method te rts) (description "Input method for Telugu script with RTS method. For the detail of RTS, see the page: . This input method is based upon the Telugu Rice Transliteration Standard (RTS) specification and its Rice Inverse Transliterator (RIT) supplement. The original RTS specification was written by Ananda Kishore and Rama Rao Kanneganti in 1992 and can presently be accessed in the \"soc.culture.indian.telugu\" newsgroup archives (see ). The RIT supplement adds alternative combinations for transliteration but, in general, does not distract from the original specification (see ). Whenever a supplemental combination conflicts with the original RTS, the RTS version has precedence and the supplemental combination is disregarded (such as 'ea' from RIT 3.0). Finally, this input method deviates slightly from the RTS in the following ways: (1) The combinations \"\@n\", \"\@2\", \"~c\", and \"~j\" yield \"�\" because their corresponding glyphs do not yet exist in Telugu's Unicode chart. (2) If it appears at the end of a word, the combination \"m\" yields \"ం\". The user can type \"m&\" to bypass this behavior and force \"m\" to yield \"మ్\".
