Following up, the same glyph appears elsewhere on the page you mention: > This duke before his voiage, calling at Fiscam (?) all his nobilitie unto him, caused them to sweare fealtie unto his yoong sonne William, whome he then at his journie betooke unto the governance of earle Gilbert, and the defense of the governour unto Henrie the French king. Why do we think it's more plausible that the words are being spelled "dw", "fwrth", "ywng", and "betwke" than "doo", "foorth", "yoong", and "betooke"? "Took" is still spelled that way today, and "poor" uses the same vowel as "forth". Whereas to the best of my knowledge, W can only appear as a vowel in Welsh.
