/**
 * Compares two strings alphabetically using locale-aware comparison.
 *
 * Applies string formatting based on options (case sensitivity, special
 * characters handling) before performing the comparison.
 *
 * @param a - The first string to compare.
 * @param b - The second string to compare.
 * @param options - Comparison options.
 * @param options.specialCharacters - How to handle special characters.
 * @param options.ignoreCase - Whether to ignore case differences.
 * @param options.locales - The locale(s) to use for comparison.
 * @param options.order - The order direction ('asc' or 'desc').
 * @returns A negative number if a < b, positive if a > b, or 0 if equal.
