LOWER function (ODF 1.2 Part 2)

Dear all,

6.19.13:

----b
However, as this function can be locale aware, results may be unexpected
in certain cases.  For example in a Turkish locale an upper case "I
without dot" U+0049 is converted to a lower case "i without dot" U+0131.
----e

The behaviour needs to be specified so as to avoid the "unexpected". 

Maybe by basing something on http://unicode.org/reports/tr21/tr21-5.html
?
