Sort by value uses a simple byte-value comparison (like the C function
memcmp()) - it doesn't implement any sort of language-specific collating
orders.  So it sounds to me like this is working as intended.

If you want (for example) accented and non accented versions of a letter
to sort adjacently, you might want to consider transforming the values
so that they sort in the desired order.
