Charles the Great / Subdued the Saxons, and did seat the French / Beyond the river Sala, in the year / Eight hundred five.

1599, William Shakespeare, “The Life of Henry the Fift”, in Mr. William Shakespeares Comedies, Histories, & Tragedies […] (First Folio), London: […] Isaac Iaggard, and Ed[ward] Blount, published 1623, [Act I, scene ii]

[…] there never was any person named Charles who was not an open, manly, honest, good-natured, and frank-hearted fellow, with a rich, clear, voice, that did you good to hear it, and an eye that looked at you always straight at the face, as much as to say: "I have a clear conscience myself, am afraid of no man, and am altogether above doing a mean action." And thus all the hearty, careless, 'walking gentlemen' of the stage are very certain to be called Charles.

1844, Edgar Allan Poe, Thou Art the Man
