Already with a single standard in a single project things have a tendency to start breaking down as soon as there's more than one developer and disagreement arises about what the text in the standard specification actually means.

That's true yeah. The seed of all the problems is assuming.

My teammates assumed System.DefaultEncoding must be some default value (UTF-8, they assumed, again) that would carry across all servers so no worries. Except no, it's "whatever encoding is configured on this machine as the default code page".
Which was the same across our networks, lucky them.
But for this one machine setup by an external contractor who had UTF-8 as default.
That one took me a while to track down...
