Source: Avoid out-of-range inputs to std::isspace()
`isspace` takes `int` but documents that the value must be representable
by `unsigned char`, or be EOF. Use a wrapper to cast to `unsigned char`
to avoid sign extension while converting to `int`. This generalizes the
fix from commit 5e8c176e2a (cmExecuteProcessCommand: Cast c to unsigned
char before cast to int, 2024-01-05) to other `isspace` call sites.
This was detected by assertions in the MSVC standard library while
processing UTF-8 text.
Issue: #25561
