Some of the special casing rules are not clear. # FINAL: The letter is not followed by a letter of category L* (e.g. Ll, Lt, Lu, Lm, or Lo). What happens if the word with the final sigma is followed by a period or comma etc. It should be final. But what about a hyphenated word? Technically it is still followed by a letter. The text needs clarification. It seems that final should be when it is followed by a space before a letter or followed by no more letters. Another issue - case folding. Case folding appears to be the same as a shift to upper followed by a shift to lower. The sigma adjustment is not necessary because the two forms are adjacent and will not affect sort sequences. The consolidation if dotted and dotless i should not impact compares in Turkish locations but the Lithuanian removal of u0307 (combining dot above) after i will affect the Lithuanian locale. However, this should not affect other locales. It is probably a good idea to do this for all locales. Carl
