Mangal font problem in Excel cells

Hindi characters in Mangal font appear differently in the formula bar and the cell. For example, when I enter "द्व द्ध" it appears as " द्‍व द्‍ध" in the cell. How to fix this problem? I would like to use only Mangal font (kindly do not suggest to use a different font as I already know that solution).

Thanks much for your help.
