title: Working with Unicode strings in Delphi 7
body: <p>I need to write a program which will browse through strings of various lengths and select only those which are written using symbols from set defined by me (particularly Japanese letters). Strings will contain words written in different languages (German, French, Arabic, Russian, English etc). Obviously there is huge number of possible characters. I do not know which structure to use for that? I am using Delphi 7 right now. Can anybody suggest how to write such program?</p>
