[Zope-dev] Character codes

Hello, when displaying the raw content of a list with this code: <dtml-call "REQUEST.set('myOptionList',['é', 'à', 'ù', 'è'])"> <dtml-var myOptionList> (The list values are extended characters for French accented letters. They may not display correctly in your mailer.) I get this output: ['\351', '\340', '\371', '\350'] So internally these characters are mapped to character codes. Where can I find reference information about this mapping system? Thanks. Alexandre
