How to convert UTF-8 byte[] to string?

Question

I have a byte[] array that is loaded from a file that I happen to known contains UTF-8.

In some debugging code, I need to convert it to a string. Is

I saw some answers at this post and it's possible to be considered completed base knowledge, because have a several approaches in C# Programming to resolve the same problem. Only one thing that is necessary to be considered is about a difference between Pure UTF-8 and UTF-8 with B.O.M..

In last week, at my job, I need to develop one functionality that outputs CSV files with B.O.M. and other CSVs with pure UTF-8 (without B.O.M.), each CSV file Encoding type will be consumed by different non-standardized APIs, that one API read UTF-8 with B.O.M. and the other API read without B.O.M.. I need to research the references about this concept, reading "What's the difference between UTF-8 and UTF-8 without B.O.M.?" Stack Overflow discussion and this Wikipedia link "Byte order mark" to build my approach.

Finally, my C# Programming for the both UTF-8 encoding types (with B.O.M. and pure) needed to be similar like this example bellow:

//for UTF-8 with B.O.M., equals shared by Zanoni (at top)
string result = System.Text.Encoding.UTF8.GetString(byteArray);

//for Pure UTF-8 (without B.O.M.)
string result = (new UTF8Encoding(false)).GetString(byteArray);
