Translate item (Material)

To send the message "I make Dirt look good", do the following where p is the Player:

localeManager.sendMessage(p, "I make " + ChatColor.GREEN + "<item>" + ChatColor.RESET + " look good",
    Material.DIRT, (short) 0, null);

In English (US), this will appear as...

...but if the player is using Español (México), it will appear as...

Let's say you want Podzol instead of Dirt. Give this a try:

if (localeManager.isBelow113()) {
    localeManager.sendMessage(p, "I make <item> look good", Material.DIRT, (short) 1, null);
} else {
    localeManager.sendMessage(p, "I make <item> look good", Material.PODZOL, (short) 0, null);
}

Note the durability value of '1' for older versions of Minecraft, rather than '0' for newer ones.

With enchantments

For an item with enchantments, like "A Diamond Sword with Impaling V", try this:

Map<Enchantment, Integer> ench = new LinkedHashMap<Enchantment, Integer>();
        ench.put(Enchantment.IMPALING, 5);
localeManager.sendMessage(p, "A <item> with <enchantment> <level>", Material.DIAMOND_SWORD, (short) 0, ench);
