I have an Asher Yazar card dedicated Le'ilu'i Nishmat HaRav 'Ovadyah Yosef A"H. At the bottom of the card is the Rav's name followed by זצוקללה"ו. I've been unable to decipher the full acronym through Googling.
The first 5 letters likely mean "זכר צדיק וקדוש לברכה"; but, I'm unable to decipher the rest.
I don't think this question is a duplicate (e.g. of this question) since I've identified a particular acronym without knowing its meaning (whereas the question cited above asks for common acronyms and their known meanings).
