TStringList.LoadFromFile Unicode

I am attempting to open a txt file to a StringList but if I open a UTF-8 format it fails to load, this is confusing because I have Unicode XE2, am I missing something stupid here?

Simple Sample

Sl := tStringList.Create;

SL.LoadFromFile(sFilePath);

For i =0 to SL.Count -1 do
  foo

but the String does not load when the txt file is UTF-8 but works fine when its in ANSI format.

Solution

  • If your UTF-8 file does have a BOM, then loading a UTF-8 file which contains an invalid UTF-8 byte sequence will produce an empty result, with no exception or indication of the failure. This is a 'feature' of the Delphi file handling. So if you see this result and your file has a valid BOM, check the content.
