This is so simple :-). Enter the text in the upper text box, and then select the Source and Destination scripts. To override the default conversion settings, select the appropriate check boxes. The Check-boxes can be activated by clicking on the respective buttons.

Default Conversion

The Converter automatically applies [if necessary] certain nativization conventions that is usually applied in the Target script, to make the text more nativized in the Target script.  This is in line with the script conventions for the Target script. For the nativization conventions for each script , refer the script specific help page.

General Options

Preserve Source

Since, the Target text is processed for nativization convention, its not possible to accurately reverse transliterate the nativized text to get the original source.  This option facilitates lossless reverse transliteration by preserving the Source text. This enables the use of various diacritics [such as caret (^), apostrophe (') ]  to preserve the source.

Remove Diacritics

This option removes the various diacritics characters from the Target text. This includes superscript/subscript numerals, and other diacritics used in the Indic Script text. Do note that it doesn't affect the Nukta based extended letters.
