Hello Everybody! I've noticed a difference between two GS version regarding Collators and Locales. Some time ago, using version 3.2.8.1, while playing around with Indexes I was able to use a collator for "es_AR". Now, while trying to do the same ini 3.4.3 version, such collator doesn't exist.

As far as I read on the programming guide, Gemstone relies on ICU library but I don't think that ICU removed collator for "es_AR" because there exists a locale for that language-country.
If I take a look at the result of IcuLocale availableLocales it returns an array which includes "es_AR".
But if I try to create a collator for this locale, an error is returned: "a ArgumentError occurred (error 2718), No predefined IcuCollator for locale 'es_AR'"

Taking a closer look at IcuCollator methods, there is one called "availableLocales". Executing it, returns an array where is not included "es_AR".
From this phrase on the Prog guide: "The classes IcuLocale and IcuCollator provide an interface to the ICU (International Components for Unicode) libraries." I expected IcuCollator and IcuLocale to work with the same locales.

So, is this behavior correct? Was "es_AR" removed by Gemstone or by ICU? How can I add my own collator for "es_AR"?

Hope I could made my self clear and sorry if I missunderstood anything here.
Thank you
