*
* - " " (ASCII 32 (0x20)) space.
* - "\t" (ASCII 9 (0x09)) tab.
* - "\n" (ASCII 10 (0x0A)) line feed.
* - "\r" (ASCII 13 (0x0D)) carriage return.
* - "\0" (ASCII 0 (0x00)) NULL.
* - "\x0B" (ASCII 11 (0x0B)) vertical tab.
*
* @param s The string to strip.
* @param char_list A string which contains the characters you want to strip.
