What is the BOM for UTF-8?

The UTF-8 BOM is a sequence of bytes at the start of a text stream ( 0xEF, 0xBB, 0xBF ) that allows the reader to more reliably guess a file as being encoded in UTF-8. Normally, the BOM is used to signal the endianness of an encoding, but since endianness is irrelevant to UTF-8, the BOM is unnecessary.

How do you detect BOM?

Does PowerShell support utf8nobom encoding?

Starting from version 6 powershell supports the UTF8NoBOM encoding both for set-content and out-file and even uses this as default encoding. Show activity on this post. When using Set-Content instead of Out-File, you can specify the encoding Byte, which can be used to write a byte array to a file.

How to test if text file is utf8 or ANSI?

Text file with lots of UTF8 special characters. I loaded it and saved it as UTF8 with no BOM. Notepad and Notepad++ interpreted it as UTF8. This means that without a BOM Notepad looks at the characters in file to determine if it is UTF8. If no special characters then it is ANSI. This is an unicode/UTF-8 test.
