Filepaths containing whitespaces broken apart in all_changed_files

Background Information

Hi everyone,
I'm working on using tj-actions/changed-files to speed up the linting workflow of an Open Source project.
The idea is to use tj-actions/changed-files to pull a list of all modified files and pass that list to a linter step:

# actions/checkout@v3 above
      - name: Get changed files
        id: changed-files
        uses: tj-actions/[email protected]
        with:
          files: |
            src/Features/*.cpp
            src/Features/*.h
            **/*.hlsl
            **/*.hlsli
      - name: List all changed files
        run: |
          for file in ${{ steps.changed-files.outputs.all_changed_files }}; do
            echo "$file was changed"
          done
# pass ${{ steps.changed-files.outputs.all_changed_files }} to linter

Problem - Filepaths with whitespace not preserved

When testing this out, I noticed some of the files I modified contained whitespaces in their filepaths, which were broken up:

For example, after modifying a file with the filepath (note the spaces in Complex Parallax Materials):

features/Complex Parallax Materials/Shaders/ComplexParallaxMaterials/ComplexParallaxMaterials.hlsli

the 'List all changed files' step prints the following:

In short, the above filepath is broken into the following:

features/Complex
Parallax
Materials/Shaders/ComplexParallaxMaterials/CRPM.hlsli

which are then passed to the linter step and break CI.

Question - How to preserve file paths containing whitespaces?

Is there a way to preserve the full pathnames?
Renaming the directories is out of the question, as I want my PR to only modify the workflow.

Currently attempting the solution proposed in #609 (comment):

@preritdas Seems you'll need to tweak the code you have to resolve the issue.

For example, you'll need to use

...
      - name: List all modified files
         run: |
           IFS=$',' read -a MODIFIED_FILES_ARRAY <<< "${{ steps.changed-files-comma.outputs.modified_files }}"
           for file in "${MODIFIED_FILES_ARRAY[@]}"; do
             echo $file
           done
           unset IFS
         shell:
           bash
