Echoing a Space Character Into a File - batch-file

Question

I want to make a batch obfuscator with no outside tools, but I have a problem with echoing the spaces into the 'obfuscated' code('obfuscated' as in separating the code letter by letter between hundreds of random characters). I have found batch obfuscators that are used with CertUtil, but they can be de-obfuscated with another file, so I really want to get this working, and I haven't really found any unique ones.
When I run my file with the input file (contains #echo off and echo test), I get the obfuscated code:
$zz$j?$z?$#z#?$z?$z###$j?j#zz?$?##j$?$?$#z$$#zjj#zzz?j#jzj#zjjzj?$#$jj?j##z##?#$$$#zjz?$zj#j$zz#jzj###$z#j#j#??##zj#z#j$?$jzjz?$j?$?##zzz#???z$$jzj#??###jz$?$j$z$?$?$?j$j?$jzzj#j#z$zz$jzz#z#$jz#?z?$$$?e$?$j?$##?#zjjjjz#j$$zjjz##$?jzjj?$##?##j$#z#zj?zzjzj$$j#$j$????$z#j#$?j?#j$$$$#jzj$$j#z#z###?j#zjz#jc$#jjz$j#$zj?#z$$?j$z$#?zz$$zz#z?##j#zz#j#z##?$#z$j?$j?z$#?#$$z??j?zj#j$##?#$zz#$$$z?z$z?jz#?j?j#z$?jhj??z?zzj##$?#j$$j#j?#$?$j$$zzzzjjz?z?##$?$$j$zz#?j#?##z#jz$z#jz$z?zzj$###z#jzjzz$##?$j??$??#?zz##?$$ojj#$j$j##?#?jzj$z#?zz##$jjjj#j#?$##j?$?j$#jzzj#?$?jz#$#z#$j???z#$?z?jzzzj$?#jzj#j$#j#??j$?jj?jzz?$#$##z$jjj#?jjz#??jz$?###$j$##$$#$$#?$?j$?z$j?j##?z$#jj?#jzjjjzz$jzjj$##z$?#$##z#$#z##$z?zz##$z?jj$#??jo#$##jjjj?$z$?#z?$##zjz$#j#zz#z?$#$##$j#j?#$#$zz$zj#j?$jjz#jjzjjz#$$j#jjz$?z?j?j#?j$#?zj?jjzzz#$?$##jfzj#?##?jjzjjz$??#zjj??j#????#z#$$$?$?##z$#$zj?jj?#?z$jzj?$j?#??zzj#$jj$?z#j???jjj#$jj$###?$$##jjz?$jf$$##z$$?jjj$##z$$jz#z#z?#j##$?$$##z?z$z$$$#jj$?zj?#jz#z$jz?$#j$?#j##z$$jz?$z$$?z#?jz?$$zz$$$#$$?#jjjjz?zj?$$j?#$#?jjj?$$?j$$$#??j?zzz#?zjz$jjzz$?zjz##j#$?z#z$??$?$?jj?###jj##$zjjj$z$?###z#z$??z#jz#zjz?$?j#j$j#zj??j#z??z$$z#$$$$##z$?#?$$jjjj#zz#j###?j??z#$#$$?j##z#$#$$z#jjzj#$#jjjz?###$???zzzz$#$z?j$$$#??z?#j$j$???z?$jz$z?z???z?j#j??$z$$#$#$#j??$$##zjj#j#$$z$$?jj?jzjzjz$$z#zz?$?j$zjzjzz$j#j$#??j???jjj##z#$$$#j$#?j?#z$#$?#zj#?$$??jj?#z#?$##jzzz?$$$zjjjzzjz#$#?#$#jz$z?$z##jjjzj?z?j???j??##$zj$zj?#zjzj##j#z$$???#$jzj#z?z??jj##??z####?#?#z??j$????$$zz#jzj?z?j?z?#z$zz??j$?zz#jj##zz##??zj?#z??$?j###?zz#zjjzj$$z#??#?$?#$jj#j?$$$j?zzjz?$?#z#z$#jj#jz$???zj$jjjz$jz#j#$zz?jj#jj?#jj###?z#$j?zzj#jz?$#zj?#?j#?z??$z??jzz?#zj??j?$z##z#j$zjz#zz?$zj$?jjz?jjj$?j$$#z#?#j?zj$$j#jj#z?z#j#?jzzz$jjj$jzjz$j#j#j#?zzzz??z#z$jz#$#z$$?jz$j#?jz??jj#jj$z#z##j$j$##$???z??j?zzjz$??j#zzz#$jj#jzj#z$z$$?$z$jzzj#$#z$#z?z$###???$$?zz$#??j$?$j#j$#?zj$jzzj??j?z?zzz##?j$?z?j$jjz$jj?z#?j##$$?zjzjj#jjj??z$?#zzj$j#??z#zz$$j?jzj#j

However, when I manually remove all of the characters, I am left with:
#echooff
echotest
Is there a way to echo spaces into a file by itself so this problem will be fixed?
My code:
#echo off
set /a N=0
:file
set /p "file=Enter filename: "
if not exist %file% echo Please try again. The file you specified does not exist.
if not exist %file% pause>nul
if not exist %file% cls
if not exist %file% goto file
cls
echo Please wait.
set /a overallfirst=1
set /a double=0
for /F "usebackq tokens=*" %%f in ("%file%") do goto start
:start
set /a "tamp=%random%"
set /a loop2=0
set /a rand=%random% %%5 +1
if %rand%==1 echo #> %tamp%
if %rand%==2 echo $> %tamp%
if %rand%==3 echo ?> %tamp%
if %rand%==4 echo z> %tamp%
if %rand%==5 echo j> %tamp%
:chars
if %loop2%==100 goto next
set /a rand=%random% %%5 +1
if %rand%==1 <nul set /p=#>> %tamp%
if %rand%==2 <nul set /p=$>> %tamp%
if %rand%==3 <nul set /p=?>> %tamp%
if %rand%==4 <nul set /p=z>> %tamp%

goto chars
:next

set "start=^<nul set /p=%chars%^>^> Obfuscated.bat"
del %tamp%
set /a loop=-1

if %overallfirst%==1 set /a overallfirst=0 & set /a double=1
I have looked for a solution, but I was unable to find one.
(I am fairly new to Batch coding so this script is not very efficient)

Answer 1

Try using <nul set /p and echo/. This post may help: Preserve spaces with <Nul set /p
