Which function returns the integer Unicode value for a character argument?

The function that returns the integer Unicode value for a character argument is AscW(). This function is specifically designed to take a character input and return its corresponding Unicode code point as an integer.

Unicode is a standard that assigns a unique numeric value to every character, providing a consistent way to encode text across different systems and languages. Using AscW(), developers can easily retrieve this integer value, which is essential in various programming scenarios where character manipulation, encoding, or comparisons are necessary.

In contrast, other options do not correctly represent functions that operate in the same manner. For example, CharValue() and CharToUnicode() are not standard functions recognized within many programming contexts for this purpose, and while UnicodeValue() might sound plausible, it doesn't exist as a recognized function in popular programming languages. Thus, AscW() stands out as the correct choice for obtaining the integer Unicode value of a character.
