  • Will bite you in the end. Trust me. I've just come from a project where we've used hack upon hack upon hack upon hack to ensure that entities get preserved in one state or another. But the trouble is that you've effectively got several layers of character encoding. In our case, we ended up with stuff in the database which contained & et al. Well, in some tables we did. In others we had UTF-8. And the search engine saw character references and turned them into latin-1. Sometimes. So you neve

    • Actually, it sounds like you are dealing with a different problem.

      We own the data that we are serving up through this web app. So it's fully normalized by the time it's parsed in this pipeline. The problem is more about keeping the entities that are in there from being converted into UTF-8.

      • You're right, I was talking about a semi-different problem, which descended into a large rant. :-)

        I'm still curious about the need for character references rather than UTF-8 bytes though. Which browsers were giving you trouble?


      • One solution to this problem is to turn all non-ASCII characters into numeric character references before writing output. This saves having to worry about the encoding of characters in binary.
        • Right, but if you postprocess the non-ASCII characters, then you're post processing the data. The constraint on this project is to: (1) load XML into a buffer, (2) parse that buffer, (3) send chunks of that buffer as-is to prevent extraenous [re-]processing.
