Description Mike Kaganski 2023-10-19 06:22:23 UTC 
Dim Statement help page [1] tells:

> String: String variable consisting of a maximum of 64,000 ASCII characters.

This is not true: the strings can have up to almost 2^31 Unicode characters (strictly speaking, the current implementation, based on rtl::OUString, can hold up to 2 147 483 642 UTF-16 code units exactly).

Oh, and I learned now, that since commit a44c9d023041c881f7858ddd9d93809dc1861313, on 64-bit systems, strings may safely contain exactly 2^31 - 1 = 2 147 483 647 characters. Not a huge difference, just getting more pedant points into karma :)
