It still is if you speak Aramaic or Hebrew.
But I speak English and it's been Jesus in English since before my time, so I'll go with established practice.
"Jesus is the Romanization of the Pharisee acronym YSHU which stands for Yimach Shimo Uezichro"
That's interesting in that it's incorrect on two counts.
It's not an acronym, and it's Greek rather than Roman.
Jesus/Ιησούς is just the Greek rendering of Joshua and/or Jesus. In Hebrew both names are rendered as Yeshua.
This no different than how the Hebrew Jacob becomes James in English or Seamus in Scottish. That's the way language operates in the real world.
