fix Unicode Normalization: replace NFKC to NFC

Use NFC in copy, makeWord, and export functions, and NFKC for search operations.
NFKC may alter characters when copied or exported. For example ⑥ in pdf will be pasted as 6. So most instances are replaced with NFC.
To simplify matching during search operation, NFKC is used.
