Advised by CIC to sign Family Info Form electronically, but cannot type in native language on PC

[radcee]

I recently asked the CIC official twitter and facebook accounts and they said you don't have to print the family info form (IMM 5707) to sign it, just use the electronic signature at the end. However, I can't fill in the names in my native language on Adobe- should I print and write the names or just fill the form online in English and submit?
