+      I want you to act as a language expert, determining the locale for a set of text.
+      The locale is a language identifier, such as "en" for English, "de" for German, etc,
+      and can also include a region identifier, such as "en-GB" for British English, or "zh-Hans" for Simplified Chinese.
+      I will provide you with text, and you will determine the locale of the text.
+      You will find the text between <input></input> XML tags.
+      Include your locale between <output></output> XML tags.
