This prepends a UTF-8 byte order mark which avoids the bug. [citation needed] UTF-8 without the byte order mark would still trigger the bug, as it is identical to the "ANSI" file. Saving as "Unicode", which in Microsoft Windows means UTF-16LE. When loading this text IsTextUnicode should (and does) return true and the text is correct.
The byte-order mark (BOM) is a particular usage of the special Unicode character code, U+FEFF ZERO WIDTH NO-BREAK SPACE, whose appearance as a magic number at the start of a text stream can signal several things to a program reading the text: [1] the byte order, or endianness, of the text stream in the cases of 16-bit and 32-bit encodings;

The byte order mark is designed so that a computer who reads it, can guess (with a reasonable probability) that the data text is probably Unicode, and;
The order of magnitude of data may be specified in strictly standards-conformant units of information and multiples of the bit and byte with decimal scaling, or using historically common usages of a few multiplier prefixes in a binary interpretation which has been common in computing until new binary prefixes were defined in the 1990s..
(Note that in a computer's memory, the order of the Hebrew characters is ב,א,מ,ת.) With an RLM added after the exclamation mark, it renders as follows: I enjoyed staying -- באמת! -- at his house. (Standards-compliant browsers will render the exclamation mark on the right in the first example, and on the left in the second.)
A Unicode character is assigned a unique Name (na). [1] The name is composed of uppercase letters A–Z, digits 0–9, hyphen-minus and space.Some sequences are excluded: names beginning with a space or hyphen, names ending with a space or hyphen, repeated spaces or hyphens, and space after hyphen are not allowed.
Microsoft was one of the first companies to implement Unicode in their products. Windows NT was the first operating system that used "wide characters" in system calls.Using the (now obsolete) UCS-2 encoding scheme at first, it was upgraded to the variable-width encoding UTF-16 starting with Windows 2000, allowing a representation of additional planes with surrogate pairs.
