I write daily in US English, Australian English, and Austrian German. Most of the time, a specific document is in one dialect/language or another: not mixed, although sometimes that's not true. I can understand that the conflation of spelling, word choices, time and date formatting, default paper sizes, measurement units, etc, etc, is convenient, and works a lot of the time, but it really doesn't work for me at all. That said, I appreciate that I occupy a very small niche.
