ColoredConsoleAppender writes UTF-8 preamble to the console on initialization #168
Description
I have an issue with ColoredConsoleAppender on WIndows 10.
After initialization it prints an extra "space" to the console at the very beginning.
It writes the preamble of UTF-8 encoding that results in a visual "space" in windows console.
After debugging I found that it happens in ActivateOptions function when setting AutoFlush property of StreamWriter to true.
If you look at sources of Console.WriteLine method, they set HaveWrittenPreamble property to true to bypass writing it by streamwriter. That's why they have no such issue.
