OK, so I guess the code should track the combining class and copy out
chunks of codepoints with the same class, something like:
int32_t prev; /* Last class transition */
uint8_t class = 0;
while ( /* iterate backward over string */ ) {
while (u_getCombiningClass(codept) == class) {
/* Get 'next' codept */
}
/* Copy codepts from 'next' to 'prev' */
}
Is that correct ?
