Text to Unicode converter






Load conversion table - click on desired button
Here's the itrans 5.3 spreadsheet and the iso based input spreadsheet for itrans conversion.
There are cells with explanation notes in the spreadsheet. As of 2026, input codes for both ITRANS and ISO are mostly the same.

Examples

Visit this page for examples of most of the codes used for both itrans 5.3 and iso based codes.

Brief example itrans 5.3 encoding
Note: itrans uses a precise mapping of input codes to output code. It is not a phonetic conversion system, nor is it meant to be. (There are many other systems that do that.) Itrans is a table-driven, customizable mapping of input words to any Unicode character sequence.

Default (original itrans 5.3 input encoding)
Enter this example text in the Enter itrans input box above: 

a aa | ka kSha || sa.nskRRit
cha{nukta} 0 9  Tha.N na.n OM
#telugu ka kha ## Toggle itrans mode
#oriya ka kha
#sanskrit dil  #hindi dil
{skier} {face-frown} {face-grin}
The above text shows these features:
  • vowels such as a aa, consonants such as ka Kha
  • Unicode code points such as {nukta}
  • explicit language markers such as #telugu
  • schwa deletion in Hindi and corresponding sanskrit example: dil
  • use of ## to toggle off/on the itrans mode. The toggle will disable itrans conversion, or use the last used language marker for itrans conversion, depending on whether it is the first ## or the second ## marker.
  • use of unicode names directly{face-grin}
  • Visit examples of many of the codes used for both itrans 5.3 and iso based codes.
The example text produces this output: Example output
