special characters issue in xml

["Ray Nainy" <ray_456@xxxxxxxxxxx>]

Hello All,

Is there a way to retrive the decimal and/or hex value of a character?
Can we scan the text in a record and check for  special characters like  , 
line feed,
carriage return?
I think decimal values 32 thru 126 represent valid/most widely used 
characters.
How can we retrieve the decimal value of the characters (dec value <32 and 
>126)?
Is there a way to identify these special characters while reading a text 
record?

I need to take care of these special characters for an xml document upload.
Since we replace & with a &amp; in xml document, all the special characters 
need
to be converted to xml standard so that the xml parser can read the data.

Thank you all in advance.

Ray
