> I always underline ш and write a line over т

Interesting. I think this style completely died out in Russia, I wasn't taught it and never really seen it outside of some old letters and documents. Interesting to hear it survived in Belarus

Our Belarusian teacher actually ш/т wrote it like that, I got it from her. It’s not very common in Belarus, either.

I think the real strongholds of this style are Serbia and [North] Macedonia. They even underline и and write a line over п (they can do this since they use ј instead of й).
