How to use "own" username in .yml files?

I'm trying to translate flarum to my own language but there's a small issue.
When I go to line 524 in core.yml, there's:

you: You

part. I tried to change it to:

you: "{username}"

However nothing shows up. ?

explain

I don't want it to say "Sen ve SoruJokeri" ^(You ^and ^SoruJokeri)
I want it to make it work like "duman ve Sorujokeri" ^(duman ^and ^SoruJokeri)

So, basically "you" should be "own username".
Couldn't find a way to do it.

If the code using that translation does not inject the username, it won't be available for you.

Unfortunately I think the "You" translation is used as-it, without any injected value. You have to use a static string with no placeholder ?

So what you are trying to do is probably not possible without adding javascript to alter the translation usage.
