Conv demo

[limelect]

Just testing Conv demo with d10.2.3
The new version (updated) does not compile with an error
function Realloc(var NewCapacity: NativeInt): Pointer; override;
realoc differ from older declaration

So I went back to your older version it had a loading error
On editproject I changed to fd:AnsiString; other wize it was jibrish

I have tried to fix the Realloc error with a {$IF CompilerVersion section, but am not sure what version it changed. I guessed 30, but I may have to change that to a different version...

TEditProjectMainForm.LoadProject does UTF8/UTF16 detection on the fly there, because older Delphi versions don't have System.IOUtils' TFile.ReadAllText and I didn't want an ugly {$IF section there, and was trying to keep Delphi 7 compatibility, but I may need to change it if it doesn't work. Though changing fd to an AnsiString may be an unclean fix if it breaks unicode support...
