With 0.3.3 I get lexer error on first line

[ghost]

Previously everything was ok (0.3.2 works), the line has "Feature: " as the beginning. It happens with more .feature files.

Can you share some failing feature files?

The file seems to be encoded as UTF-8 with BOM. Gherkin (the parser) seems to not like the marker and does not expect it at the start of the file. Try saving that file again as UTF-8 without BOM. I could get your feature to load properly by doing so.

This is a known problem on Gherkin: cucumber/gherkin#100. We can't do much about it on Cucumber.js itself.

Hi @jbpros. Would it be ok to reopen this issue until cucumber/gherkin#100 is fixed?

Here's the cryptic error message I see when a feature file includes a UTF-8 BOM (http://en.wikipedia.org/wiki/Byte_order_mark):

...\node_modules\gherkin\lib\gherkin\lexer\en.js:1008
      throw new Error("Lexing error on line " + this.line_number + ": '" + content + "'. See http://wiki.github.com/cucumber/gherkin/lexingerror for more information.");

I am experiencing the same thing on the latest version 0.4.7. Just bumping this issue up in hopes it'll get fixed soon.
