| # Unicode has multiple ways how to encode certain glyphs. UD data must always use the canonical way. | |
| # For example, 'č' is one character (U+010D = LATIN SMALL LETTER C WITH CARON) and it is OK because it is the canonical encoding of this character. | |
| # The non-canonical way is 'č' (two characters: U+0063 = LATIN SMALL LETTER C, U+030C = COMBINING CARON). | |
| # On the other hand, 'с̌' (two characters: U+0441 = CYRILLIC SMALL LETTER ES, U+030C = COMBINING CARON) looks the same but it cannot be normalized to a single character because it is supposed to be Cyrillic. | |
| # In the example below, we use the Cyrillic+Combining sequence in FORM and Latin+Combining in LEMMA. Only the latter should be reported as an error. | |
| # sent_id = 1 | |
