'#' in artifact name are replaced

Hello, it seems like ‘#’ character in artifact names of gitlab ci are replaced by ‘_’ I can’t find any mention of it in the doc.

ie :

[...]
   artifacts:
    name: "PA-SBO-SB-##$CI_COMMIT_TAG" 
[...]

generates a PA-SBO-SB-__v0.1.0 zip file and not PA-SBO-SB-##v0.1.0
