find and replace space with nonbreaking space

[bajqo]

I am from Slovakia and slovak language need at the end of column not to have single letter or two letter word. It must be before whole word in next line. 

Can you help me with sentence to find and replace all spaces with nonbreaking spaces for all single letter od two letter words?

example:

Ako sa
máš.

Zajtra a
pozajtra.

replace to:

Ako
sa<NBSP>máš.

Zajtra a
a<NBSP>pozajtra.

Thank you.

I think that topic might be of interest to you, your solution might be close to @loukash last post (1/20/2023)…

Not even that…  
We've been explicitly through Czech (and thus also Slovak, even Polish) prepositions/conjunctions before:

And before that:

… and maybe some more.

Thank you it works great. But what about two-character prepositions?

Have you solution for that too @loukash?

No jo, co s nimi…? 

You may need to create an explicit regex pattern to include those prepositions. I'm not skilled enough in regex to type a pattern off the top of my head. You will have to look up the syntax yourself or wait for someone else to chime in.

No tiež niesom skúsený dosť aby som to napísal sám. Len či náhodou to už niekto nevyriešil.

In my case just wait. I'm not skilled at all in regex to type pattern.

But thak you. Partial solution is still better than no solution.
