title: All ranges of Unicode letters?
body: <p>Each Unicode code point is assigned to a <a href="https://www.compart.com/en/unicode/category" rel="nofollow noreferrer">character category</a>. I'm looking for a list of ranges which has the category "Letter". Best would be a CSV in the format "FROM_CODEPOINT;TO_CODEPOINT" with all ranges that define letters.</p>
