The Tabulate(p, n) command generates strings over integer ranges. It constructs the string $\mathrm{cat}\left(\mathrm{seq}\left(p\left(i\right)\,i=1..n\right)\right)$. For an integer i in the range $1..n$, the expression $p\left(i\right)$ must evaluate to a string of type character. Typically, p is of type procedure. The second argument n must be a non-negative 32-bit integer.

All of the StringTools package commands treat strings as (null-terminated) sequences of $8$-bit (ASCII) characters.  Thus, there is no support for multibyte character encodings, such as unicode encodings.
