Symfony ICU translation trailing newline after the translated message - symfony

Question

I followed the official Symfony documentation on how to translate messages using the new ICU message format.
Inside the messages+intl-icu.pl.yaml file I have the following entry:
pages:
show:
ratings_title: Opinie
ratings_count: >
{count, plural,
=0 {brak opinii}
one {jedna opinia}
few {# opinie}
other {# opinii}
}
Which is consumed as follows:
<div>
<h1>{{ 'pages.show.ratings_title'|trans }}</h1>
<sub>({{ 'pages.show.ratings_count|trans({'count': count}) }})</sub>
</div>
Which results in:
<div>
<h1>Opinie</h1>
<sub>(brak opinii
)</sub>
</div>
While the expected output should be:
<div>
<h1>Opinie</h1>
<sub>(brak opinii)</sub>
</div>
So my question is: how to remove that trailing newline character after the translated message?

Answer 1

Ok this was simply due to misconfigured YAML file. In order to strip YAML's trailing newline inside a multi-line string I should have written the translation entry as follows:
pages:
show:
ratings_title: Opinie
ratings_count: >-
{count, plural,
=0 {brak opinii}
one {jedna opinia}
few {# opinie}
other {# opinii}
}
Notice the use of >- instead of >
