Recursively replacing non-standard charecters from folders and files on win10


I have many folders with sub-folders of files I get from colleagues with special and even hidden characters like these:

Non standard chars: {µ, 市, ', &, 「 , invisible char, Ü, é, ... }

I am looking for a script or a windows tool that would rename all sub-folders and files in one go by replacing any non-standard character to a standard one according to characters in List X. Bonus: even better would be, if the tool would check List R, and use a replacement rule, if one is defined. If not, it should just replace the non-standard char with "_".

List X: {A-Z, a-z, 0-9, (, ), [,],-, _}
List R: {é->e , ü->u, ä->a, @->at,...} (Replacement rules)

Appreciate any hint to a tool or script.


Solution

  • How's this? Replacing specific characters, then anything not between space and tilde or tab, like the unicode snowman.

    echo hi | set-content filä.txt,filé.txt,fil☃.txt # in script or ise
    $pairs = ('ä','a'), ('é','e'), ('[^ -~\t]','_')
    dir -r | where name -match '[^ -~\t]' | rename-item -newname {
      $name = $_.name
      foreach ($pair in $pairs) {
        $name = $name -replace $pair
      }
      $name
    } -whatif
