If you wish to add English text to the Sanskrit text, enclose it between '##'. For example:
The characters . , : ; ( ) < > [ ] @ $ ^ & ~ + | = / ? ! " ` - * if following \ (backslash) are also treated as English text:
\ (backslash) followed by a word is considered a command in "LaTex", which is the encoding language of .itx files. So, words starting with a backslash are ignored by Itranslator, therefore you do not get output for those words, even if they are not commands.
Similarly, the % (percentage mark) is used to add remarks in .itx files. Anything following the % is a remark and ignored.
