WideStringList and old and new Delphi

[Andrzej 0]

What is best way to do following:

I need of list of Unicode strings for my Json5 parser. In new Delphi from 2009 i can use Tstringlist and load ,save to stream automatic convert between utf8 and utf16le.

For old Delphi I must create WideStringList and convert between utf8 and utf16.

Next I must conditionally define JsonStringList as Tstringlist and TwideStringList?

I think, no need stringlist, rather parsing strings, parse widestring,utf8string,unicode and utf8 files.

Be aware that WideString is OS-controlled so is much slower in creation/disposal.

Old Delphi probably dont have stringbuilder and operations like stringlify would be slow..
