Xqt added a comment. Using empty strings with PS --- Try the follwing example invoking the Python command shell. With cmd you can use en empty string like `pwb shell foo "" bar -noimport` For PS you have to escape the empty string in this form using

Xqt added a comment. @Aram: I see, you are using Powershell to invoke the python command. I was able to reproduce the reported behavior with Powershell and it seems that PS ignores empty strings. Please use the `cmd` comand propt and it will work as expected. TASK DETAIL

Aram added a comment. @Xqt, I have updated python to the latest version `3.12.3` and tried `-3.12-64` and `-3.10-64` launchers. Both launchers were the same. This is escaping one: PS C:\Pywikibot> python pwb.py -simulate replace -page:ئانیشک -site:wiktionary:ckb -regex

Xqt added a comment. Just an idea to circumvent this sys.argv problem is to use a preleading linespace but does not work if the template is in the first line on the page: python pwb.py -simulate replace -page:ئانیشک -site:wiktionary:ckb -regex "\r?\n{{wikipedia}}\n?" "\n"

Xqt added a comment. Does an escaping work: `python pwb.py -simulate replace -page:ئانیشک -site:wiktionary:ckb -regex "{{wikipedia}}\n?" \"\" -summary:"Replace test"` Are you able to install another python like Python 3.11 or 3.12? You may run different versions using the `py`
