Bug#26711 "Binary content 0x00 sometimes becomes 0x5C 0x00 after dump/load"

Browse Source 
Problem: "SELECT INTO OUTFILE" created incorrect dumps for BLOBs,
so "LOAD DATA" later incorrectly interpreted 0x5C as the second
byte of a multi-byte sequence, instead of escape character.
Fix: adding escaping of multi-byte heads.

  Flagging character set as dangerous for escaping.
