Summary

Closes #33410

: as a delimiter produced invalid CSS selectors. «» are not valid XML 1.0 names. _ should be valid in all scenarios. The Root still has an identifierPrefix option if that causes conflicts.

How did you test this change?

Search&replace for «, », \u00AB, and \u00BB

Alternative to #33421. The difference is that this also adds an
underscore between the "R" and the ID.

The reason we wanted to use special characters is because we use the
full spectrum of A-Z 0-9 in our ID generation so we can basically
collide with any common word (or anyone using a similar algorithm,
base64 or even base16). It's a little less likely that someone would put
`_R_` specifically unless you generate like two IDs separated by
underscore.
