You can use EngDots feature to insert English letters or words inside the Tamil text. Place two consecutive dots surrounding the English letters. This will allow the parser to not ignore these words, and only the remaining text will be converted.
Suppose you want to a sentence like this:
எனக்கு English, தமிழ் ரெண்டும் தெரியும்
you have to type:
enakku ..English.., thamiz reNdum theriyum
EngDots would be helpful in several scenarios:
- To mention someone in your tweet
- To include a URL
- For some occasional "peter" :-)
- etc. etc. etc.
