杰克·
贾西亚 is the standard Chinese rendering for the very common Western full name Jack Garcia. The middle dot · separates given name from surname in Chinese transliterations of foreign personal names — type it as a fullwidth interpunct, not a regular period.
杰克 (Jack) is one of the most common transliterated first names alongside
迈克 (Mike) and
汤姆 (Tom).
