We have a problem in Telugu Wikipedia. While in Transliteration mode, it prints English character also besides printing Telugu character. For example, if I press 'd' key, it should print the Telugu character "ద్", where as it is printing "ద్d". This is observed in the last two days. I am using Windows OS and Chrome 61.0.
This problem is not there in the editors of Telugu Wikisource or Wikidata.org.
