github.com/ik5/gobom (go): Package gobom contains several methods to detect BOM type.  BOM stands for Byte Order Mark. It is a standard by the Unicode organization to understand the type of encoding is standing in front of us, by placing non printable chars that explains if an encoding is UTF16 or UTF32, and what is the endian that it uses. The standard does not recommend to place a BOM to UTF8, but it supports that as well.  This library was created for helping me detect if something contain a BOM, and that's it. It does not do anything else, and there is no plan for anything other then detecting it.  How does the library works?  The library can use io.Reader, and also "pure" byte slices and rune slices in order to detect the type of BOM.  Please note: If a BOM is not detected, then it will return "Unknown". If a buffer is too small to detect BOM type it also returns "Unknown"
