Entering Hindi numbers in Writer
There seems to be a bug in Libreoffice that when Options-----Language settings-----Complex text layout-----General options and changed the numerals to Hindi, the numerals display in Arabic script.
I have gotten round the issue by changing the numerals type to System, instead of Hindi.
Hindi number digits are in the Unicode range U+0966 to U+096f [PDF]. Given font support, under Linux you can enter these via CTRL+SHIFT+U+<digits>. Other platforms will use a different key combination.
Right alt key plus number keys do the job for me when in hindi bolnagri keyboard layout mode
This is especially useful for those using QWERTY rather than InScript layout. Thanks for reporting.
