Can it be used in terms of SEO?

Question

Search Engine Optimization

Hello knowledgeable people.
Tell me, please:
From the point of view of the usual layout (printing), a word (preposition) of less than 4 characters remaining at the end of a line, or the first word of a sentence, as well as a dash, flying to the next line, is considered at least a sign of bad tone.
To avoid this, I use all sorts of things in the html layout:

 
<span style="white-space:nowrap"></span>
<nobr></nobr>
&shy;

The essence of the question:
what is the status of using such elements from the point of view of SEO:
(use and don’t worry - robots are smart) / (can be used, but with restrictions) / (not allowed under any circumstances)?
In the case of option 2 - tell me where to read / look.
