April 2016 2 Unicode Strings File Format EDK II Unicode files are used for mapping token names to localized strings that are identified by an RFC4646 language code. The format for storing EDK II Unicode files is UTF-16LE. The character content must be UCS-2. The UNI files contain UCS-2 characters stored in either UTF-8 or UTF-16LE format on disk. Strings ends are determined by the first of the following items found: * a control character * a comment * the end of the file * a blank line Comments may appear anywhere within the string file. All the files must begin with a Unicode BOM character. Note: Please make sure you select an editor that supports UCS-2 characters that can be stored in a UTF-8 or UTF-16LE file. 2.1 Common EBNF The following EBNF uses quoted (double quotes) encapsulated characters to represent UCS-2 string literals. In the following definitions, the semi-colon is used to denote a comment. <US> ::= " " <Letter> ::= {(\u0041-\u005A)} ; Characters A - Z {(\u0061-\u007A)} ; Characters a - z <Digit> ::= (\u0030-\u0039) ; Characters 0 - 9 <MS> ::= <US>+ <ME> ::= {<MS>} {<EOL>} <CommentLine> ::= "//" <US>* <PCHars> <EOL> <BlankLine> ::= <EOL> <Chars> ::= (\u0001-\uF6FF) <PChars> ::= (\u0021-\uF6FF){(\u0020-\uF6FF)} {<OpChar>} <OpChars> ::= "\x" [{<HexDigitU>}]{4} "\" <VChars> ::= (\u0021-\uF6FF) 4 Redacted Formerly "Meta-Data UNI Files".
