And if you give more real-life examples, then the regex can be made more robust.
I tested both steps on the examples I gave, and it works perfectly fine on any 2+ single letters (not "a", "A", or "I") next to each other.

Good to hear. If those two-spaces only occur in the letterspaced words... then your life is easier, no fancy regex needed!
And can I ask:
Which OCR are you using?
Can you share an example page or something from this specific book?
I'd be interested in taking a look.

Which language? I was assuming English and no accents.
Yes, of course, different languages are going to have their own little single-letter-word quirks...
Like in Spanish, you'd want to avoid 'y' (since that = "and").
But then you would just swap out the [aAI] regex with a [yY] (or equivalent).
Accents, similar situation. You'll just have to make much uglier and harder-to-understand regex.

Yep, it's just helpful when someone searches for a solution in the future for "how do I fix a gap between letters?".

You cannot regex this away. You have to do it by hand because you will combine letters/words you do not want to.
Use the regex for searching. But do the fixing by hand.

You can use Regex to do the vast bulk of the corrections, then manually fix the edge cases.
Better/faster to do:
- 95% correct with a 2-step regex.
- 5% manually find/correct/fix.

And as usual, I've been pondering on how to get Spellcheck Lists to help you solve this issue more efficiently.
Instead of using a '+' or '¬', it might be better to use a period:
Code:
<p>A decent example of S.w.i.t.z.e.r.l.a.n.d that I found within a G.e.r.m.a.n example.</p>
This allows you to spot all of them easily in Sigil's or Calibre's Spellcheck Lists:
All merged words right there in a simple list.
Although the period will bring a few other minor issues (like "a.m." or "p.m."), but the amount of time you'll save is massive.
