Thanks for your research!
I only meant, but didn't explain very well (at all) that it is no
longer good enough to assume that the whole world speaks American
English. While there is a good case for English-based programming
languages, programming is about end-users. They don't know and don't
want to know about limitations of 8 bits or ASCII's definition of the
alphabet, nor do clients or project managers. They just want to be
able to read things in their own language. We're getting there slowly.
I was actually surprised to find that English isn't the most spoken
language. But my intended point was it is only one of three major
languages. I am British and I live and work in Spain, producing
multilingual websites in Catalan, Spanish, English and, occasionally,
German and French.
