StreamWriter and UTF-8 Byte Order Marks

Question

I\'m having an issue with StreamWriter and Byte Order Marks. The documentation seems to state that the Encoding.UTF8 encoding has byte order marks enabled but when files are

Answer 1

As someone pointed that out already, calling without the encoding argument does the trick. However, if you want to be explicit, try this:

using (var sw = new StreamWriter(this.Stream, new UTF8Encoding(false)))

The key is to construct a new UTF8Encoding(false), instead of using Encoding.UTF8Encoding. That's to control if BOM should be added or not.

This is the same as calling StreamWriter without the encoding argument, internally it's just doing the same thing.
