Using the Hindi keyboard and typing the following sequence of keystrokes below I get :
Shift + 4 र्
Shift + 4 र्र्
Shift + 4 र्र्र्
This is the way I understand what is occurring above :
- The key Shift + 4 inputs at once the Hindi character र (j) combined with the virama diacritics ् (d). In fact, if one types these two characters in sequence, with the Hindi keyboard, one gets the character र्.
