And Perl, and probably other languages.

That would have been my preference, but C++ (starting in C++17)
and C (starting in C23) have already specified apostrophes.  C++
uses underscores as part of the syntax for user-defined literals,
also introduced in C++17.

The apostrophe is the standard thousands separator in Switzerland.
I don't know how much that influenced the decision in C++.
