<p>Le <b>Multinational Character Set</b> (<b>MCS</b>, ou jeu de caractères multinational) est un <a href="Codage_des_caract%C3%A8res" title="Codage des caractères">codage de caractères</a> créé par <a href="Digital_Equipment_Corporation" title="Digital Equipment Corporation">Digital Equipment Corporation</a> pour le <a href="Terminal_informatique" class="mw-redirect" title="Terminal informatique">terminal informatique</a> <a href="VT220" title="VT220">VT220</a>. C'est une extension 8-bits de l'<a href="ASCII" class="mw-redirect" title="ASCII">ASCII</a> qui apporte divers caractères accentués, des symboles monétaires et d'autres caractères absents de l'ASCII 7-bits. Le MCS est seulement une des <a href="Page_de_code" title="Page de code">pages de code</a> implémentée dans le National Replacement Character Set du VT220<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup><sup class="reference cite_virgule">,</sup><sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>.
</p><p>Les extensions de l'ASCII étaient alors très nombreuses (le National Replacement Character Set gérait une douzaine de jeux de caractères destinés à autant de langues européennes), mais le MCS est considéré comme à la fois l'ancêtre de l'<a href="ISO/CEI_8859-1" title="ISO/CEI 8859-1">ISO/CEI 8859-1</a> et de l'<a href="Unicode" title="Unicode">Unicode</a><sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>.
</p><p>Un comparaison de MCS avec l'ISO/CEI 8859-1 et les 256 premiers codes de l'Unicode révèle plus de similitudes que de différences. Les différences avec ISO/CEI 8859-1 sont :
