前32 个控制字符的详细解释:
NUL (null)
SOH (start of heading)
STX (start of text)
ETX (end of text)
EOT (end of transmission) - Not the same as ETB
ENQ (enquiry)
ACK (acknowledge)
BEL (bell) - Caused teletype machines to ring a bell. Causes a beep
in many common terminals and terminal emulation programs.
BS (backspace) - Moves the cursor (or print head) move backwards (left)
one space.

line. On Unix systems, moves to a new line
AND all the way to the left.
VT (vertical tab)

output device is a printer).
CR (carriage return) - Moves the cursor all the way to the left, but does
not advance to the next line.
SO (shift out) - Switches output device to alternate character set.
SI (shift in) - Switches output device back to default character set.
DLE (data link escape)
DC1 (device control 1)
DC2 (device control 2)
DC3 (device control 3)
DC4 (device control 4)
NAK (negative acknowledge)
SYN (synchronous idle)
ETB (end of transmission block) - Not the same as EOT
CAN (cancel)
EM (end of medium)
SUB (substitute)
ESC (escape)
FS (file separator)
GS (group separator)
RS (record separator)
US (unit separator)
