Script override ( View | Script Override menu) is a very useful feature using which, you can read the text of one Indian script in another Indian script or ISO15919 script. For example, let's say you received an email as a .BRH document which contains Hindi text. Let's say you understand Hindi language but not comfortable in reading devanagari script. Now, using the script override feature you can read the Hindi text in another familiar script say Kannada.
All the Indian scripts are derived from the Brahmi script, which is also the underlying concept in Baraha. Baraha uses a common code (BRHCODE) for representing all the Indian languages. So, it is possible to convert text from one script to another. Most of the characters exist in all the scripts. Some characters may not exist in some scripts in which case, Baraha tries to map to the nearest possible character. If it is impossible to map a character, it gets ignored. This underlying principle is used to provide the Script override feature of Baraha.
Script override is useful for learning Indian scripts.
