Should I use UTF-8 with BOM?

Should I use UTF-8 with BOM?

Use of a BOM is neither required nor recommended for UTF-8, but may be encountered in contexts where UTF-8 data is converted from other encoding forms that use a BOM or where the BOM is used as a UTF-8 signature.

How do I find my BOM character?

To check if BOM character exists, open the file in Notepad++ and look at the bottom right corner. If it says UTF-8-BOM then the file contains BOM character.

How do I encode in UTF-8 without BOM?

Open the file you want to verify/fix in Notepad++ In the top menu select Encoding > Convert to UTF-8 (option without BOM) Save the file.

What is UTF-8 no BOM?

The UTF-8 encoding without a BOM has the property that a document which contains only characters from the US-ASCII range is encoded byte-for-byte the same way as the same document encoded using the US-ASCII encoding. Such a document can be processed and understood when encoded either as UTF-8 or as US-ASCII.

How to add and remove Bom from UTF-8 file?

This article shows you how to add, check and remove the byte order mark (BOM) from a UTF-8 file. The UTF-8 representation of the BOM is the byte sequence 0xEF, 0xBB, 0xBF (hexadecimal), at the beginning of the file.

What is a UTF-8 signature ( Bom )?

What is a UTF-8 signature (BOM)? Some applications insert a particular combination of bytes at the beginning of a file to indicate that the text contained in the file is Unicode. This combination of bytes is known as a signature or Byte Order Mark (BOM).

What is the byte order mark in UTF-8?

Optionally, the UTF8Encoding object provides a byte order mark (BOM), which is an array of bytes that can be prefixed to the beginning of the byte stream that results from the encoding process. If a UTF-8 encoded byte stream is prefaced with a byte order mark (BOM), it helps the decoder determine the byte order and the transformation format or UTF.

When do you need to use BOM for Unicode?

A: Here are some guidelines to follow: A particular protocol (e.g. Microsoft conventions for .txt files) may require use of the BOM on certain Unicode data streams, such as files. When you need to conform to such a protocol, use a BOM. Some protocols allow optional BOMs in the case of untagged text.
