You just need to know which encoding is always right
This is by design
All XML processors must support at least UTF-8 and UTF-16.
The support of other encodings, is encouraged but not required. However, many parsers implement supports for all ISO 8859 encodings, as well as for the most used Japanese, Chinese, and Korean ones.
