Displayed width of UTF-8 strings in Modern C++

Applying different operations on a string using Fork and Exec.

Calculate sunrise, set times, twilights, wait for any such events, and poll whether it is day or night.

Use this code to count the length of a string. This function splits the string into chunks of size_t to improve performance. It reduces the number of iterations, resulting in faster detection of the null character ('\0').
