@beny996 We need more information here.

Is this Cyrillic or Latin?

I suspect we might need to update https://github.com/nodejs/nodejs.org/blob/main/crowdin.yml#L15-L20

[beny996]

@bmuenzenmeyer It is latin. Sorry for the delay.

[bmuenzenmeyer]

Serbian (latin) added in crowdin

This PR will need to be rebased or recreated now that https://github.com/nodejs/nodejs.org/pull/6850 merged.

[beny996]

I will recreate the PR. @bmuenzenmeyer
