Windows Glyph List 4

Windows Glyph List 4, or more commonly WGL4 for short, also known as the Pan-European character set, is a character repertoire on recent Microsoft operating systems comprising 652 Unicode characters. 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.

As of 2004, WGL4 characters are the only ones guaranteed to display correctly on recent versions of all major platforms of Microsoft Windows. Some Unicode characters may be missing from default installations of Windows 9x (such as Armenian and Georgian) or of Windows XP (such as Ethiopian and Runic), but WGL4 glyphs are found on all major platforms of Microsoft Windows.

Because many fonts are designed to fulfill the WGL4 set, this set of characters is likely to work (display as other than replacement glyphs) on many computer systems. For instance your browser is probably able to draw all the characters in the table below, compared to the many missing characters you may see in other articles about Unicode.
