𦑺𦏸（上初師反下雉知反皆正字體也經作差池俗用非正言𦑺𦏸者由邂逅也並從羽形聲字也）。

Irregular and uneven (𦑺𦏸: the first [character] is *tsh(o)* + *sh(i)* in fanqie; the second is *zh(i)* + *zh(i)* in fanqie. Both are standard character forms. In the sūtra it is written as 差池, which is vulgar usage and not standard. Saying 𦑺𦏸 is akin to 'accidental' (xèhòu); both derive from 羽 and are phono-semantic characters.)
