Those kanji don't occur in Japanese, so they wouldn't have a commonly understood pronunciation. For example, the first non-Japanese kanji in your text is 驘. This is not part of the Japanese inventory of kanji, but it is an alternate form of the kanji 騾, which exists (sort of) in Japanese and is pronounced ra. But that doesn't mean this pronunciation works for 驘. Its almost like looking at Rune symbols and asking how they would be pronounced in English.
