随风

也来个不能显示特殊字符,
去除首尾空格
:

@echo off
set "str=   ab     c    "
call :lis %str%
pause
:lis
echo ☆%*☆
goto :eof

随风

极其臃肿.
:

@echo off
set "str=   a\b c&>! .  "
call :lis
set flag=1
:lis
set var=
for /l %%i in (1 1 100) do (
   if defined str (
   call set "var=%%var%%%%str:~-1%%"
   call set "str=%%str:~0,-1%%"
))
set "str=%var%"
for /f "tokens=*" %%a in ("%str%") do set "str=%%a"
if not defined flag goto :eof
echo "%str%"
pause
