While more analysis i found that 0 width is assigned to most of the marks
characters.
1. In my humble opinion it is valid. We can not assign equal Width same as
Base characters to Marks character.
Font with "Decided Fixed width" or "0 Width" characters should be
considered as a Monospace.
2. Other reasons is compatibility with other font editors.
