toLocaleLowerCase Method (Windows Scripting - JScript)
Returns a string where all alphabetic characters have been converted to lowercase, taking into account the host environment's current locale.
The required stringVar reference is a String object, value, or literal.
The toLocaleLowerCase method converts the characters in a string, taking into account the host environment's current locale. In most cases, the results are the same as you would obtain with the toLowerCase method. Results differ if the rules for a language conflict with the regular Unicode case mappings.
