Duke Charles was shorter and stouter than Duke Philip, but well formed, strong in arm and thigh. His shoulders were rather thick-set and a trifle stooping, but his body was well adapted to activity. The contour of his face was rounder than that of his father, his complexion brunette. His eyes were black and laughing, angelically clear. When he was sunk in thought it seemed as though his father looked out of them. Like his father's mouth was his, full and red. His nose was pronounced, his beard brown, and his hair black. His forehead was fine, his neck white and well set, though always bent as he walked. He certainly was not as straight as Philip, but nevertheless he was a fine prince with a fair outer man. When he began to speak he often found difficulty in expressing himself, but once started his speech became fluent, even eloquent. His voice was fine and clear, but he could not sing, although he had studied the technique and was fond of music. In conversation he was more logical than his father, but very tenacious of his own opinion and vehement in its expression, although, at the bottom, he was just to all men. In council he was keen, subtle, and ready. He listened to others' arguments judicially and gave them due weight before his own concluded the discussion. He was attentive to his own business to a fault, for he was rather more industrious than became a prince. Economical of his own time, he demanded conscience of his subordinates and worked them very hard. He was fond of his servants and fairly affable, though occasionally sharp in his words. His memory was long and his anger dangerous. As a rule, good sense swayed him, but being naturally impetuous there was often a struggle between impulse and reason. He was a God-fearing prince, was devoted to the Virgin Mary, rigid in his fasts, lavish in charity. He was determined to avoid death and to hold on to his own, tooth and nail, and was his father's peer in valour. Like his father, he dressed richly; unlike him, he cared more for silver than for jewels. He lived more chastely than is usual to princes and was always master of himself. He drank little wine, though he liked it, because he found that it engendered fever in him. His only beverage was water just coloured with wine. He was inclined to no indulgence or wantonness. "At the hour in which I write his taste for hard labour is excessive, but in other respects his good sense has dominated him, at least thus far. It is to be hoped that as his reign grows older he will curb his over-strenuous industry." As to the duke's sympathies, Chastellain regrets that circumstances have turned him towards England. Naturally he belonged to the French, and it was a pity that the machinations of the king, "whose crooked ways are well known to God, have forced him into self-defence. Yet on his forehead he wears the fleur-de-lys."
