You mean \p{N}

Download and unzip 
http://www.unicode.org/Public/6.0.0/ucdxml/ucd.all.flat.zip into say 
e:\temp\ucd.all.flat.xml. Then run the following query to find all 
characters in category Nd (or mutatis mutandis, any other category; for 
a single-letter category like 'N', match all entries where @gc starts 
with N)

for $c in doc('ucd.all.flat.xml')//*:char[@gc='Nd']
return <c cp="{$c/@cp}" gc="{$c/@gc}" name="{$c/@na}"/>

for example by using the command

java -Xmx1024m -cp e:\saxon\saxon9he.jar net.sf.saxon.Query -t 
-q:e:\temp\test.xq !indent=yes

(it's a large file so it needs the extra memory).

Here's a sample from the output:

<c cp="0AE6" name="GUJARATI DIGIT ZERO" gc="Nd"/>
<c cp="0AE7" name="GUJARATI DIGIT ONE" gc="Nd"/>
