What I tried to say is, if you need ID_Start, then parse ID_Start from DerivedCoreProperties.txt. That's more stable (and easier than parsing the pieces and deriving # Lu + Ll + Lt + Lm + Lo + Nl # + Other_ID_Start # - Pattern_Syntax # - Pattern_White_Space yourself. For example, at least one of the derivation formulas (for Alphabetic) is changing from 6.3 to 7.0. markus
