After updating to OS Sequoia 15.7 (a routine security update), my Opera text encoding completely broke – for nearly every website in any language, almost every character displays as a question mark in a box. Updating my Opera version to current (122.0.5643.24) did not resolve the issue. No other web browsers on my machine appear to have been affected. An add-on to manually change text encoding did not have any effect.
How can this be repaired (without loss of current tabs, history, and other data)? How could this have happened in the first place?
Thank you.
