The DQLOCALEGUESS function
evaluates the input character value using the specified locale guess
definition in each of the locales that are loaded into memory. An
applicability score is generated for each locale in the locale list.
If multiple locales hold the highest score definition, or none of
the locales have the guess definition, the return value is the first
locale in the locale list. The name of the locale that is returned
depends on which locales are loaded into memory.
