Migrating Large Scale Applications from ASCII to Unicode?

bobm asks: "We've been asked to migrate our newer applications to Unicode. My biggest issue is that if we start storing user data in unicode we will no longer be able to provide complete updates the legacy (pure ASCII) systems. This is important in that we are currently updating > 25k customers a day and managment does not want that to be affected. I also haven't found a clean way to provide multilanguage data mining that can return a single language output. This doesn't even begin to address issues like data validation and display issues. (note: we currently handle the web pages in multiple language sets but require the data to be in ascii form.) I've spent some time on Unicode.Org but I really haven't found any real world discussions on people doing this on a large scale (>1Tbyte databases)."

    The delivering of food to the Afghanistan people is very helpfull indeed, very helpful as a PR-instrument to the US-government.
    What are the real reasons behind the war ? Think for yourselves instead of believing CNN (Which is only interested in advertisement-money, not in delivering the full story)
    Who is in control of The US anyway ? Who funded BOTH candidates for
    US-presidency ? Answer : the Oil-industry, which is very keen on taking
    control of more Oil-wells located in the middle east.
    THINK FOR YOURSELVES : BE CRITICAL,SURF THE NET,FIND OUT ABOUT HISTORY AND MAKE UP YOUR MIND.

    No you don't.

    Your comments record with all those -1 scores indicate that you're just a lameass.

    In fact I don't even know why I am wasting my time replying to this. Gotta go, see you never.

    XML is just the current flavour of the month.
    If you use it you have to make sure you have all
    the correct parsers and meta data set up plus
    its such a bloody verbose language that you'll
    find your data files bloating to a horrid
    degree.

    Unicode is 2 bytes per char, ascii is 1. A simple
    converstion program is trivial to write, you
    simply have to find the mappings.

    Why is this modded as informative?

    It's 100% offtopic.

    The poster has a terabyte DB - MySQL is a toy, there's no way it could handle that much data, therefore your post is offtopic. (Nobody cares that MySQL doesn't handle Unicode, because the poster wouldn't be using it anyway.)
