Just to be clear, TAB *only* appears in utf-8 as the encoding for the actual TAB character, not as a part of any other character's encoding. The only bytes that can appear in the utf-8 encoding of non-ascii characters are starting with 0xC2 through 0xF4, followed by one or more of 0x80 through 0xBF.
