If FileLocator Pro is unable to detect a file's encoding (through the BOM or XML header) it needs to estimate the best encoding to try.
Auto detect UTF-8 files
With the auto-detect feature active FileLocator Pro will read the first 2KB of the file to see if any specific UTF-8 character sequences can be found. If they are found it reads the file as UTF-8 otherwise it defaults to reading the file as ASCII text. However, it is possible to override this behaviour and specify UTF-8 as the default format for given file types.
