FWIW, there are some cases where you do need to escape baskslashes in titles.
One example is a title about UNC paths in Windows:
Problem going to \\server\share
becomes:
Problem going to \server\share
unless you double up the first pair of backslashes:
Problem going to \\\\server\share
Our forum is about a file manager, so this example isn’t entirely contrived. That said, it is still rare for it to matter, and the problem is still small and cosmetic, so it may still not be worth fixing. We can certainly live with it.
