I need to clean up file names on upload. Both for image fields, other file fields and IMCE file manager. The transliteration module is not yet ported to Drupal 8 and the community does not seem to agree on how to implement the core transliteration in Drupal 8.

Do I have to make a custom module for this, or is there a simpler way?

Right now, Drupal 8 seems to allow both spaces and special characters in filenames. I know about the module File (Field) Paths, but it will have to be set up for every file field on every content type. I don't think it will work with IMCE.

It seems that the module already mentioned is now covered by Drupals security advisory policy:

Transliterate filenames for uploads - https://www.drupal.org/project/transliterate_filenames

Stable releases for this project are covered by the security advisory policy.

8.x-1.3 Stable release covered by the Drupal Security Team released 1 July 2019


I applied a Drupal 8 core patch from this page. It seems to work fine. It adds a new option to /admin/config/media/file-system: File transliteration option Drupal 8

This option enables transliteration for all future uploads to all file fields. It also works for inline images when Enable image uploads is enabled (for the text-format). I don't know if the patch affects IMCE, since IMCE was not installed on my test installation.


There is a module for that https://www.drupal.org/project/transliterate_filenames

Transliteration for all uploading files (includes fields and ckeditor inline upload)

How to use: just enable module as usual. All new file names will be transliterate to Latin characters.

  • The module is stable now and it works: 1.It replaces spaces in file names 2.Adds a counter for duplicate files. Apr 6, 2020 at 8:29

Just use this module. This module is based on the blog post by Alexander Belov, but simplified for a less specific use case. https://drupal.org/project/filename_transliteration
