Hi Marek,
The current version of Decipher doesn't support the Rupee symbol, so you would need to select the numbers without it for now.
However, this is updated in v2.2 due for release this year with the option to select India in the "locale". This will recognise the Rupee symbol and how the number separation differs from the UK.
Thanks
Ben
