Remove all formatting charactersf except for paragraph and cr/lf

[fig000]

I am working on a word document that was created by a third party. We have received it and we're trying to reformat it. I suspect that it's been handled by a template or some other software. We need to reformat it due to the weird characters in the document. I would like to remove all formatting characters except paragraph and cr/lf. The posts I've seen have only shown a list of characters to remove, ot "everything but". can anyone help me remove all characters "but" those I've just mentioned? Thanks, Fig000
