How to make text not editable & also I want to make it outline!

Hi Guys,

Looks like easy question. But to me it is difficult...

I want to keep my text not editable format (Because, i have few symbols. they are approved by client). And this text should make outline at the end if I use "command + shift + O"

Example: If you see the below screenshot, the text "SYMBOL" should be in text format, but not in editable. And also that text has to be made outline if I use "command + shift + O"

awaiting for your smart answers.

Thanks & regards,
