Improve error when parsing file

[stephanerenou]

When the plugin parses the file, it reports a stacktrace that does not contain the file that is being parsed. It would be usefull to have the path to the file in the below first line?
Invalid UTF-8 start byte 0x92
at [Source: (File); line: 10, column: 33]
