China DOS Union

As the title says. To expand on that, how can I search for and identify Chinese content in text?

I’ve been researching this problem for a year. If you don’t believe me, search for my first post, hehe

o_O

Does it have to be pure batch processing?

First use character substring extraction to get a single character, then use your (echo string&echo.)|findstr /o ".*" to determine whether it is two bytes
(use character substring extraction to determine the number of characters, then use (echo string&echo.)|findstr /o ".*" to determine the number of bytes; if they are equal, then it does not contain double-byte characters)

input:Chinese
4

input:English
7

input:Chinese+English
12

@echo off

set/p input=input:

set str=%input%



:loop

set str=%str:~1%

set/a n+=1

if not "%str%" == "" goto loop



for /f "skip=1 delims=:" %%i in ('^(echo "%input%"^&echo.^)^|findstr /o ".*"') do set/a l=%%i-5

if %n% == %l% (

  echo String %input% does not contain double-byte characters

) else (

  echo String %input% contains double-byte characters

)

pause>nul

exit

Hehe, I also only discovered findstr's o parameter while researching this, but this makes the code a bit too long, so I wanted to ask whether there’s any other method

A somewhat simpler VBS script would also be fine

A long time ago a moderator taught us a method:

After reading the first character, first use batch processing to determine whether it is a space. If it is not a space, then use:
echo %x%>3.txt and then check whether the file size of 3.txt is one byte or two bytes to determine whether it is a Chinese character.

Now there is also the findstr /o method

Looking forward to an even simpler method ^_^

echo 望大师,傅.看见fdg|awk "{a=gsub(/[\x80-\xff]/,\"\");print a/2\" Chinese characters\"}"

6 Chinese characters

A VBS script wouldn’t be much simpler either:

@echo off

set/p input=:



>ascw.vbs echo Wscript.echo ascw(wscript.arguments(0))



for /f %%i in ('"cscript //nologo ascw.vbs %input%"') do (

  if %%i leq 255 (

    echo %input% is not a double-byte character

  ) else (

    echo %input% is a double-byte character

  )

)

pause

To zh159:
What do you input in this case?

:ok我
ok我 is not a double-byte character
Press any key to continue . . .

ascw can only process characters one by one; to determine a whole sentence you need other statements to work with it
So in my post #9 I only wrote “is not a double-byte character / is a double-byte character”, and not “contains or does not contain double-byte characters”

To determine a string:

@echo off

set/p input=:



>ascw.vbs echo str=wscript.arguments(0):result="does not":for i=1 to len(str):if ascw(mid(str,i,1))^>255 then:result="":exit for:end if:next:Wscript.echo result^&" contain double-byte characters"



for /f %%i in ('"cscript //nologo ascw.vbs %input%"') do echo %input% %%i

pause

VBS can use regular expressions to determine character types, but I still don’t know how -_-|||

Is there a more complete one? I can’t imitate it from just a single line
