def _narrow_unichr(code_point):
    """Retrieves the unicode character representing any given code point, in a way that won't break on narrow builds.

    This is necessary because the built-in unichr function will fail for ordinals above 0xFFFF on narrow builds (UCS2);
    ordinals above 0xFFFF would require recalculating and combining surrogate pairs. This avoids that by retrieving the
    unicode character that was initially read.

    Args:
        code_point (int|CodePoint): An int or a subclass of int that contains the unicode character representing its
            code point in an attribute named 'char'.
