No, they are letters of the Latin alphabet interpreted abstractly.
They are not even required to form words; as a string of mathematical
letterlike symbols, your “𝐦𝐚𝐭𝐡𝐞𝐦𝐚𝐭𝐢𝐜𝐚𝐥” above might mean a
product of 12 vector variables and read accordingly: [em ei ti: eitch
i: em ei ti: si: ei el] in English, or [em uh te ush e em uh te i tse
uh el] in Russian (which borrows the pronunciation of single Latin
letters from French and/or German).
