How To Properly Handle Utf 8 Bom Files In Nodejs Dev Community 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. according to the unicode standard, the bom. Utf 8 always has the same byte order, [6] so its only use in utf 8 is to signal at the start that the text stream is encoded in utf 8, or that it was converted to utf 8 from a stream that contained an optional bom. the standard also does not recommend removing a bom when it is there, so that round tripping between encodings does not lose.

Many standards only support utf 8, e.g. json exchange requires it (without a byte order mark (bom)). [36] utf 8 is also the recommendation from the whatwg for html and dom specifications, and stating "utf 8 encoding is the most appropriate encoding for interchange of unicode " [ 4 ] and the internet mail consortium recommends that all e‑mail. Learn about the different encoding forms of unicode, including utf 8, utf 16, utf 32 and their variants. find out how to convert, use and interpret unicode data with or without a byte order mark (bom). In the utf 8 encoding, the presence of the bom is not essential because, unlike the utf 16 or utf 32 encodings, there is no alternative sequence of bytes in a character. the bom may still occur in utf 8 encoding text, however, either as a by product of an encoding conversion or because it was added by an editor.

The end result is as follows: by default, files are encoded with utf 8 without bom. utf 8 with bom is selected only for specified file types for which it is known that the bom doesn’t cause any problems. so basically there is will be a utf 8 bom whitelist. the remainder of this document explains the reasons behind this decision. 46. file will tell you if there is a bom. you can simply test it with: printf '\ufeff \n' | file . dev stdin: utf 8 unicode (with bom) text. some shells such as ash or dash have a printf builtin that does not support \u, in which case you need to use printf from the gnu coreutils, e.g. usr bin printf.
