Windows Glyph List 4, or more commonlyWGL4 for short, also known as thePan-European character set, is acharacter repertoire onMicrosoft operating systems comprising 657Unicode characters, two of them for private use. Its purpose is to provide an implementation guideline for producers of fonts for the representation ofEuropeannatural languages; fonts that provideglyphs 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^[update], WGL4 characters were the only ones guaranteed to display correctly onMicrosoft Windows. More recent versions of Windows display far more glyphs.

Because many fonts are designed to fulfill the WGL4 set, this set of characters is likely to work (display as other thanreplacement glyphs) on many computer systems. For example, all the non-private-use characters in the table below are likely to display properly, compared to the many missing characters that may be seen in other articles about Unicode.

The repertoire, defined byMicrosoft, encompasses all the characters found inWindows code pages1252 (Windows Western),1250 (Windows Central European),1251 (Windows Cyrillic),1253 (Windows Greek),1254 (Windows Turkish), and1257 (Windows Baltic), as well as characters fromDOScode page 437.

It does not cover the combining diacritics used by Vietnamese-relatedcode page 1258, the Thai letters used incode page 874, Hebrew and Arabic letters covered by code pages1255 and1256, or the ideographic characters used by code pages932,936,949 and950.

It also does not cover the Romanian lettersȘ,ș,Ț, andț (U+0218–B), which were added to several of Microsoft's fonts forWindows Vista (long after the WGL4 repertoire was originally defined).

In version 1.5 of the OpenType Specification (May 2008) four Cyrillic characters were added to the WGL4 character set:Ѐ (U+0400),Ѝ (U+040D),ѐ (U+0450) andѝ (U+045D).^[1][2][3]
