PropertyValueAliases.txt. 564 -> Removed duplicate script entries from SyntheticPropertyValueAliases.txt: 565 Cari, Cham, Kali, Lepc, Lyci, Lydi, Olck, Rjng, Saur, Sund, Vaii 566 +

SyntheticPropertyValueAliases.txt) 578- uprops.icu (uprops.h) only provides 7 bits for script codes. 579 In ICU 4.0 there are USCRIPT_CODE_LIMIT=130 script codes now. 580 There is none above 127 yet which is the script code for an 581 assigned Unicode character, so ICU 4.0 uprops.icu does not store any 582 script code values greater than 127. 583 However, it does need to store the maximum script value=USCRIPT_CODE_LIMIT-1=129 584 in a parallel bit field, and that overflows now. 585 Also, future values >=128 would be incompatible anyway. 586 uprops.h is modified to move around several of the bit fields 587 in the properties vector words, and now uses 8 bits for the script code. 588 Two other bit fields also grow to accommodate future growth: 589 Block (current count: 172) grows from 8 to 9 bits, 590 and Word_Break grows from 4 to 5 bits. 591- renamed property Simple_Case_Folding (sfc->scf) 592 + nothing to be done: handled as normal alias 593- new property JSN Jamo_Short_Name 594 + no
