Well, after a lot of discussion I got convinced that Lazarus should give a try at the UTF-8 mode of the RTL when this appears, and this might be very useful for our usage of TStringList, TComponent, TStream, etc. I think this solution has major problems, but it was claimed that my proposed solutions have much worse problems, so in the end I concluded that we should try the UTF-8 mode of the RTL when it appears. But this does not mean that LazUtils would not be useful then. My proposals to add UTF-8 routines to the RTL and even FCL were rejected, so we UTF-8 users would need to be stuck with only whatever routines Embarcadero invents. That's not nearly good enough and not nearly fast enough. UTF8LowerCase is very superior to the existing RTL LowerCase. To start with, the RTL in existing release doesn't even have a UTF8String LowerCase (no idea about 2.7). Also, UTF8LowerCase has a second parameter to specify the language, so we can test and support Turkish without having to change our locale to turkish, and it outperforms SysUtils.UnicodeLowerCase by 250% aprox in my Mac, and it has zero external dependencies while depending on zero initialization code, zero global variables and having 1k lines of code (half of them comments), which is not that much. As you can see it vastly outperforms even what the UTF-8 mode of the RTL would offer for this. Just like UTF8LowerCase, other things provided by LazUtils will also be useful options for Lazarus and other libraries/applications, regardless of FPC offering something similar. And then I think that everyone will be happy. People that want Delphi compatibility (excluding string and PChar, since they will not match in the RTL mode used by Lazarus) will be happy, they can use RTL routines and get compatibility. Lazarus will still be using string and TStringList, TComponent, etc. -- Felipe Monteiro de Carvalho -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
