They are stored in UTF-8 as 2 bytes, the EURO SIGN at dec 164, oct 144, hex A4 (in ISO 8859-15) as 3 bytes. In the ISO encodings or MacRoman they take just one byte. So for US Americans and Englishfolks, writing in English, UTF-8 makes no difference in file size, not even in presentation. As exchange format it's great: you don't have to run a dozen of tests to see whether it's some ISO or proprietary Mac or MS encoding. The binary lunacy inside the file makes it obvious. When using characters outside of US ASCII.
I see. Ok that makes sense.
> For LaTeX it makes a big difference. It makes you think that LaTeX can work with all Unicode characters. In reality it's 1 % or less, it becomes a bit more when you use specialised variants like ArabTeX, FarsiTeX, cjkTeX, pTeX, etc.
That's true. I hadn't thought about that it could be construed as misleading.
Ok. I'm convinced, at least for the default out of the box encoding. For my own personal one, it's simpler because I don't ever have to worry about switching between XeLaTeX and pdfLaTeX except for adding/removing the relevant packages. (And yes, I know about ifxetex etc. :-) )
