- Add optional extra_word_break_chars field (sorted UChar32[]) to icu_BreakIterator struct, stored as a sorted array for efficient lookup - icu_BreakIterator_new accepts optional 3rd argument (Python str) that is parsed into a sorted UChar32[] via insertion sort; only applies to UBRK_WORD - icu_BreakIterator_dealloc frees the extra chars array - New find_extra_word_break() inline helper scans a UTF-16 segment for the first matching extra-break codepoint using U16_NEXT + linear search - BreakIterState gains extra_break_active/seg_start/seg_end sub-segmentation state fields (zero-initialized by memset in break_iter_state_init) - break_iter_state_next refactored from while loop to for(;;) to drain sub-segments before fetching more ICU data; extra break within an ICU word segment causes the piece before it to flow through normal hyphen-joining logic while the tail is deferred; trailing-hyphen detection on sub-segments enables hyphen-joining with subsequent ICU segments - Fast path: num_extra_word_break_chars == 0 → single comparison, zero overhead - Tests added covering: letter extra break char, count_words/split2, adjacent breaks, multiple chars, None arg, surrogate-pair extra break char Co-authored-by: kovidgoyal <1308621+kovidgoyal@users.noreply.github.com> Agent-Logs-Url: https://github.com/kovidgoyal/calibre/sessions/c003ae42-1e56-4dbb-9ef2-9f1645b76c70
