[Routing] Fix options utf8

[maxhelias]

By the way, a configuration-block in the versionadded causes an edge effect.
I don't know how we can fix it.
Example : https://symfony.com/doc/4.3/components/routing.html#unicode-routing-support

By the way, a configuration-block in the versionadded causes an edge effect.

Please add it below the configuration-block as it belongs to all configuration formats, not just one.

EDIT: Hmm, no I think it will not change anything.
@javiereguiluz ca you please have a look here? Thank you!

@OskarStark, also this versionadded block is not present on master branch, it's weird

As we discussed in Symfony Slack ... this is not going to be easy to fix (or even possible). Instead of fixing the code error, in #11696 I propose to simplify this. Let's only mention the annotations case, which is what most people use.

We always try to only use small versionadded/deprecated. It should be removable without missing any documentation. This is why most only say "Feature X was introduced in Symfony Y" or "Feature X was deprecated in favor of Z in Symfony Y". So I would just remove the complete configuration block from the directive, if people use a previous version they should visit a previous version of the docs imo

I agree with you, I'm closing in favor #11696
