• AI hallucination drives Soundslice to build unexpected ASCII tab import feature

  Why English doesn’t use accents. - English spelling was heavily shaped by Norman French scribes post-1066, who preferred letter combinations (e.g., sh, th) over diacritics to represent non-Latin sounds.\n. - English inherited this diacritic-free approach, resulting in complex and sometimes ambiguous spelling without accent marks.\n. - French, influenced later by Renaissance printers like Geoffroy Tory, introduced systematic diacritics (acute accents, cedillas, circumflexes, diaereses) to clarify pronunciation and preserve traditional orthography.\n. - The Norman French legacy ironically removed English from diacritic traditions despite French’s increased accent use.\n. - This history explains English’s reliance on multiletter graphemes rather than diacritics, shaping its unique orthographic complexity.. .
