First of all, Unicode itself is a code page.

Support for other code pages is usually there for backwards compatibility.

  Please pardon my ignorance on the subject ...

  I was wondering if someone could direct me to some (highly) technical documentation of how code pages work, in particular to Windows systems? I want to research/understand, exactly why there is still a need for code pages given the existence of Unicode.

  I have just started a full time position, fresh out of university, that requires me to research localization on windows ce platforms. If this platform is Unicode based, why is there a need for code pages?

  I understand that code pages provide mappings of user inputs, but if everything is Unicode, why is this necessary - since all characters in Unicode are unique!

  Information pertaining to the complete process, from input to font display would be greatly appreciated.

  I have been researching this and still do not have a solid answer, only parts.

  Thank you,
