Most of the time you will not have to worry about the byte-order mark in UTF-8. In this situation, the BOM is often called a UTF-8 signature. However, the BOM may still occur in UTF-8 encoded text, either as a by-product of an encodingĬonversion or because it was added by an editor to flag the content as UTF-8. In the UTF-8 encoding, the presence of the BOM is not essential because, unlike the UTF-16 encodings, there is noĪlternative sequence of bytes in a character. The byte-order mark indicates which order is used, so that applications can immediately decode the content. You can see that the order of the two bytes that represent a single character is reversed for big endian vs. Each 2-digit hexadecimal number represents a byte in the stream of text. The picture below shows the bytes used in a sequence of two-byte characters. To communicate which byte order was in use, U+FEFF (the byte-order mark) was used at the start of the stream as a magic number that is not logically part of the text the stream represents.

16-bit code units can be expressed as bytes in two ways: the most significant byte first ( big-endian) or the least significant byte first ( little-endian). The BOM, when correctly used, is invisible.īefore UTF-8 was introduced in early 1993, the expected way for transferring Unicode text was using 16-bit code units using an encoding called UCS-2 which was later extended to UTF-16. With the introduction of U+2060 WORD JOINER, there's no longer a need to ever use U+FEFF for its ZWNSP effect, so from that point on, and with the availability of a formal alias, the name ZERO WIDTH NO-BREAK SPACE is no longer helpful, and we will use the alias here. "109" = "BE_FileExists ( path )|File Exists|Checks if the file or folder given in the path exists and returns True or False.The name BYTE ORDER MARK is an alias for the original character name ZERO WIDTH NO-BREAK SPACE (ZWNBSP). This function doesn't send files to the trash or recycle bin, so use with caution. "108" = "BE_FileDelete ( path )|File Delete|Deletes the file at location path. "107" = "BE_FolderCreate ( path )|Folder Create|Creates a new folder at the location path." To set non-text data use BE_ClipboardSetFile" You only need to apply a single format when setting the clipboard. When setting a type it's best to copy a sample and then use BE_ClipboardFormats to see what types are used. Clipboard formats are usually set by the application and depend on the content types. "106" = "BE_ClipboardSetText ( text format )|Clipboard Text Set|Sets the clipboard to the text and applies a clipboard format.
To get other types use BE_ClipboardGetFile" The function will only deal with text objects, so other clipboard types are ignored.
"105" = "BE_ClipboardGetText ( format )|Clipboard Text Get|Tries to convert the item on the current clipboard, designated by the format passed to the function. "104" = "BE_ClipboardFormats|Clipboard Formats|Returns a return delimited list of the formats of the content of the current clipboard." "103" = "BE_VersionAutoUpdate|Version Auto Update|The text of the plugin number, formatted as an 8 digit number, eg 00010712" "102" = "BE_Version|Version|Returns the plugin version number as text, eg 1.1.3"
