pattern value specification

I have to wite an application that must run on Win and Unix.

I have toi describe some pattern value. I read some documentation and some 
preious Q&A here and in google group. A question remain for me. What's the 
better way to use for specifying this pattern value, independent of 
platform:

for digits:    [0-9]  or   \d   for example 12d   [0-9]{1,12} or \d{1,12}
for enter:    &#xD or  \n    for example 12dEnter15a    
\d{1,12}
[A-Z]{1,15}

Please help me.
Thanks.
