Supported text encodings?

[gavinwy]

Per the W3C XML 1.0 Standard, it says that all XML parsers have to support at minimum UTF-8 and UTF-16 support. I'm not seeing a list of supported encodings in the docs, and figuring it out by reading the source code directly is a bit beyond me at the moment, so I'm wondering what, if any other encodings beyond UTF-8 and UTF-16 are supported? I'm also curious as to how serde-xml-rs would react if given UTF-16 content that didn't have a BOM; Would it accept such content or error out? I know that the XML Standard requires XML in UTF-16 to use a BOM, but in practice that doesn't always happen.

Thanks very much!

Thanks @gavinwy for the question.

This crate relies on the xml crate, so it supports the same encodings, namely UTF-8, UTF-16, ISO-8859-1 and ASCII (obviously). It doesn't work directly with UTF-16BE or UTF-16LE because they don't have byte-order marks.

I've made a PR that adds these details to the documentation. It also updates the version of the xml crate, since I just noticed that 1.0 just came out three days ago.
