The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

This entry of Joel on Software titled "The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)" is as it says, so if you are a programmer, read it, (No Excuses!).

Some phrases from the article:

It does not make sense to have a string without knowing what encoding it uses


How do we preserve this information about what encoding a string uses? Well, there are standard ways to do this. For an email message, you are expected to have a string in the header of the form

Content-Type: text/plain; charset="UTF-8"

For a web page, the original idea was that the web server would return a similar Content-Type http header along with the web page itself -- not in the HTML itself, but as one of the response headers that are sent before the HTML page.
