How to centralize navbar title

My app’s navbar title is in Kurdish (which is right to left), I found out that byt removing “class=title” class half of dots of letter ‘پ’ that couldn’t appear, now can appear.
I use dir=“rtl” in tag for sure.
I used "class=“right” to make it right, and it worked, but now I desire to make it to the center.
I tried "class=“center” and "class=“center sliding”, but they didn’t work for me.
Any solutions?

I don’t use content block or blocks
