Set the collation strength used in a UCollator. The strength influences how strings are compared.

Example of use:

.       UCollationResult result;
.       UChar *source, *target;
.       UErrorCode status = U_ZERO_ERROR;
.       UCollator *myCollation = ucol_open("en_US", status);
.       if (U_FAILURE(&status)) return;
.       ucol_setStrength(myCollation, UCOL_PRIMARY);
.       u_uastrcpy(source, "abc");
.       u_uastrcpy(target, "ABC");
.       // result will be "abc" == "ABC"
.       // tertiary differences will be ignored
.       result = ucol_strcoll(myCollation, source, u_strlen(source), target, u_strlen(target));
