Question
I want batch file to replace this symbol "=" with this symbol "?" in files or variables
For example:

العربية
Deutsch
한국어
Português
Russian@echo off
set file="=test.exe"
set name2=%file:==?%
ren %file% %name2%
(((if you give my code for variables it will be better)))
La solution 2
@ECHO OFF
SETLOCAL
set "junk=hello=this=is=the=original="
set "junk=q%junk%q"
:again
for /f "tokens=1*delims==" %%a in ("%junk%") do if not "%%b"=="" set "junk=%%a?%%b"&goto again
set junk=%junk:~1,-1%
echo result:%junk%:
GOTO :EOF
Need to get sneakier if there are successive "=" though...

There is extensive discussion about this and related issues at http://www.dostips.com/forum/viewtopic.php?f=3&t=1485. There are quite a few proposed solutions.
My REPL.BAT utility would seem like a great option, except there are potential problems when trying to capture the result back into an environment variable. FOR /F can be used, but it has issues with new line characters, as well as complications when the result includes ! (and possibly ^) characters and delayed expansion is enabled.
So I decided to write a variant of REPL.BAT called REPLVAR.BAT with the following features:
Note - The utility is intended for extended ASCII values. The variable should contain a value that maps to the active code page. Also, the final output must be compatible with the active code page, otherwise an error is raised.
The utility is pure script that is a hybrid of JScript and batch. It should work on any modern Windows machine from XP onward. Full documentation is embedded within the script.
Here is a trivial example of usage:
@echo off
setlocal enableDelayedExpansion
set "input=1 + 1 = 3!"
call replVar input output "=" "<>" L
echo(!output!
--OUTPUT--
1 + 1 <> 3!
I originally posted the code at http://www.dostips.com/forum/viewtopic.php?f=3&t=5492, but I am including it here as well:
@if (@X)==(@Y) @end /* Harmless hybrid line that begins a JScript comment
::************ Documentation ***********
::REPLVAR.BAT version 1.4
:::
:::REPLVAR InVar OutVar Search Replace [Options]
:::REPLVAR /?[REGEX|REPLACE]
:::REPLVAR /V
:::
::: Performs a global regular expression search and replace on the contents of
::: variable InVar and writes the result to variable OutVar.
:::
::: REPLVAR.BAT works properly with delayed expansion enabled or disabled.
:::
::: REPLVAR.BAT treats the source variable value as extended ASCII. The value
::: should map properly to the active code page. Unicode source values that
::: do not map to the active code page will be silently transformed to a new
::: value that does map to the active code page. The result of the search and
::: replace must be compatible with the active code page, otherwise an error
::: is raised.
:::
::: The maximum supported output string length usually approaches the 8191
::: maximum for most strings. But it could be significantly less if the output
::: string contains many % " \r or \n characters, as they must be temporarily
::: expanded into 2 or 3 bytes. Also, ^ and ! characters are temporarily
::: expanded into 2 bytes if delayed expansion is enabled.
:::
::: REPLVAR.BAT returns with ERRORLEVEL 0 upon success, and ERRORLEVEL 1
::: upon error. If the A option is used and the input was not altered then
::: OutVar is undefined and ERRORLEVEL set to 2.
:::
::: Each parameter may be optionally enclosed by double quotes. The double
::: quotes are not considered part of the argument. The quotes are required
::: if the parameter contains a batch token delimiter like space, tab, comma,
::: semicolon. The quotes should also be used if the argument contains a
::: batch special character like &, |, etc. so that the special character
::: does not need to be escaped with ^.
:::
::: If called with a single argument of /?, then prints help documentation
::: to stdout. If a single argument of /?REGEX, then opens up Microsoft's
::: JScript regular expression documentation within your browser. If a single
::: argument of /?REPLACE, then opens up Microsoft's JScript REPLACE
::: documentation within your browser.
:::
::: If called with a single argument of /V, case insensitive, then prints
::: the version of REPLVAR.BAT.
:::
::: InVar - The name of a variable containing the source string.
:::
::: OutVar - The name of a variable where the result should be stored.
:::
::: Search - By default, this is a case sensitive JScript (ECMA) regular
::: expression expressed as a string.
:::
::: The search is conducted using the regular expression g (global)
::: and m (multilline) flags.
:::
::: JScript regex syntax documentation is available at
::: http://msdn.microsoft.com/en-us/library/ae5bf541(v=vs.80).aspx
:::
::: Replace - By default, this is the string to be used as a replacement for
::: each found search expression. Full support is provided for
::: substituion patterns available to the JScript replace method.
:::
::: For example, $& represents the portion of the source that matched
::: the entire search pattern, $1 represents the first captured
::: submatch, $2 the second captured submatch, etc. A $ literal
::: can be escaped as $$.
:::
::: An empty replacement string must be represented as "".
:::
::: Replace substitution pattern syntax is fully documented at
::: http://msdn.microsoft.com/en-US/library/efy6s3e6(v=vs.80).aspx
:::
::: Options - An optional string of characters used to alter the behavior
::: of REPLVAR. The option characters are case insensitive, and may
::: appear in any order.
:::
::: I - Makes the search case-insensitive.
:::
::: L - The Search is treated as a string literal instead of a
::: regular expression. Also, all $ found in Replace are
::: treated as $ literals.
:::
::: B - The Search must match the beginning of a line.
::: Mostly used with literal searches.
:::
::: E - The Search must match the end of a line.
::: Mostly used with literal searches.
:::
::: A - Only return a value if the input was altered. If not altered,
::: then ERRORLEVEL is set to 2.
:::
::: X - Enables extended substitution pattern syntax with support
::: for the following escape sequences within the Replace string:
:::
::: \\ - Backslash
::: \b - Backspace
::: \f - Formfeed
::: \n - Newline
::: \q - Quote
::: \r - Carriage Return
::: \t - Horizontal Tab
::: \v - Vertical Tab
::: \xnn - Extended ASCII byte code expressed as 2 hex digits
::: \unnnn - Unicode character expressed as 4 hex digits
:::
::: Also enables the \q escape sequence for the Search string.
::: The other escape sequences are already standard for a regular
::: expression Search string.
:::
::: Also modifies the behavior of \xnn in the Search string to work
::: properly with extended ASCII byte codes.
:::
::: Extended escape sequences are supported even when the L option
::: is used. Both Search and Replace support all of the extended
::: escape sequences if both the X and L opions are combined.
:::
::: REPLVAR.BAT was written by Dave Benham, with assistance from DosTips users
::: Aacini and Liviu regarding complications due to JScript's use of unicode vs.
::: cmd.exe's use of extended ASCII. REPLVAR.BAT also uses a modifed form of the
::: safe return technique developed by DosTips user jeb. Updates to REPLVAR.BAT
::: will be posted to the original posting site:
::: http://www.dostips.com/forum/viewtopic.php?f=3&t=5492

ren %file% %name2%
But, ren command seems not to work. Will it rename file =test.exe to ?test.exe ?
