Replaced regex with backrefs package in search plugin (#8034)

Browse Source 
Use Re in all places in the search plugin except where Unicode
properties are desired (checking for Chinese chars). Use Backrefs'
`bre` to check for Unicode properties. To minimize any differences,
explicitly use `script` as Backrefs uses `script_extensions` (or `scx`)
by default with `Is*` properties.
