Word wildcard problem

[Leonatus]

Maybe that's the wrong forum, but I didn't find a better suiting one!
My problem:
In many languages, especially french and italian, direct speech begins simply with a dash at the beginning of the paragraph, such as:

Text, text, text:
– Speech, speech...

At translating, I want to replace the characters indicating direct speech by chevrons (» as opening, « as ending characters). Of course, it is simple to replace the dashes at the beginning of a paragraph by the opening chevron. But, in the say french book, the end of the direct speech is frequently not indicated otherwise as by a new paragraph.
So, what I want to achieve is to find paragraphs beginning with "»", but not ending with "«" (some do, due to previous search and replace operations, so I have to mark this explicitely). To this end, I suppose I have to use wildcards.
I tried for example:

(»*[!«]^13){1}

and this one (others do likewise) finds the end of paragraphs not consisting in a closing chevron, but jumps over several paragraphs, until finding one that doesn't end with such a chevron.
So, how can I restrict the search to first paragraph that begins with an opening chevron, but ends without a closing one?
Is there a Word crack able to assist me?

Well, the Word wildcards are a thing very special...
Trying further, I found this one that works:

Search for (with wildcards):
(»*[!«])(^13)
Replace with:
\1«\2

Maybe it`s useful to others!

For those to whom it may concern:

I found that my pattern above mentioned sometimes sets (for reasons I ignore) closing chevrons («) at the end of a paragraph that contains no opening chevron (») at all, and that are superfluous. To remove those, I invented this one:

Search for (with wildcards):
(^13[!»]@)«
Replace with:
\1

Good luck!
