strict comparing for image files works fine but for .txt file fails in CI (but works fine localy)

@need-build-with-VIPS
  Scenario Outline: it should update the preview content if the file content is updated (content with UTF chars)
    Given using <dav-path-version> DAV path
    And user "Alice" has uploaded file "filesForUpload/lorem.txt" to "/lorem.txt"
    And user "Alice" has uploaded file with content "ओनक्लाउड फाएल शेरिङ्ग एन्ड सिन्किङ" to "/lorem.txt"
    When user "Alice" downloads the preview of "/lorem.txt" with width "32" and height "32" using the WebDAV API
    Then the HTTP status code should be "200"
    And the downloaded image should be "32" pixels wide and "32" pixels high
    And the downloaded preview content should match with "unicode-fixture.png" fixtures preview content
    Examples:
      | dav-path-version |
      | old              |
      | new              |
      | spaces           |

Perhaps my libvips library on Mac works a little differently than in CI. @individual-it, could you generate the unicode-fixture.png file on your laptop using a similar version of apt-get install libvips42? Or I can change this check using a tolerance.

how to do it:

• upload file like here: And user "Alice" has uploaded file with content "ओनक्लाउड फाएल शेरिङ्ग एन्ड सिन्किङ" to "/lorem.txt"
• curl -vk -u alice:123456 -o unicode-fixture.png 'https://cloud.opencloud.test/remote.php/webdav/lorem.txt?x=32&y=32&preview=1'
• replace file to tests/acceptance/fixtures/unicode-fixture.png

@ScharfViktor can you try with a bigger size preview? because for me (using the docker container) it does not work. It only returns squares:

[ScharfViktor]

I got the fixure image on a remote Linux computer with libvips42 installed. The test passed locally, let's see what CI says.

[individual-it]

yes, but now there are no special non-latin UTF characters.

I think this is a bug, the preview should also work with nepali and other characters

[ScharfViktor]

true, preview works only with latin and cyrillic

[ScharfViktor]

but the test doesn't work. even when we use Latin

[individual-it]

you are checking the size in every other test except of here, any special reason for that?
theoretically we don't need to check the size, because we are trying to match the file anyway. so if the size would be wrong the test would also fail
