In the section "Search Algorithm" within this section, case fold mapping appears as step 11. Normalization appears as step 13.
Since normalization (particularly the compatibility mapping) may change the character sequence, it would be better to apply the case folding after the normalization, particularly if the case fold is language-sensitive.
