I don't think there is any difference between what you call text and binary, what you report sounds more like the difference between UTF-16 and UTF-8.
technically, the 2:1 ratio you describe is variable, but I understand for all practical purposes in ASCII, you could say that it is pretty much a constant. a Unicode code-point in UTF-8 consumes up to 3 bytes (6 according to specification), and any single Unicode character (grapheme) can be a representation of 1 or more code points. so, for instance, text predominantly made of typical CJK (Chinese-Japanese-Korean) characters will take up 1.5 times more space in UTF-8 compared to UTF-16. 2017/07/10 12:40、David Adams via 4D_Tech <4d_tech@lists.4d.com<mailto:4d_tech@lists.4d.com>> のメール: So, with text, my export was 24.66GB and as text it was 12.35GB, nearly 50% smaller. ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
