Windows Glyph List 4

Pan-European character set specified by Microsoft

Windows Glyph List 4, or more commonly WGL4 for short, also known as the Pan-European character set, is a character repertoire on Microsoft operating systems comprising 657 Unicode characters, two of them private use. Its purpose is to provide an implementation guideline for producers of fonts for the representation of European natural languages; fonts that provide glyphs for the entire set of characters can claim WGL4 compliance and thus can expect to be compatible with a wide range of software.
