      Description

      TextSource in the org.apache.beam.sdk.io package can handle UTF-8 encoded files, and when the file contains byte order mark (BOM), it will preserve it in the output. According to Unicode standard (http://www.unicode.org/versions/Unicode5.0.0/ch02.pdf): "Use of a BOM is neither required nor recommended for UTF-8". UTF-8 with a BOM will also be a potential problem for some Java implementations (e.g., https://bugs.java.com/bugdatabase/view_bug.do?bug_id=4508058). As a general practice, it's suggested to use UTF-8 without BOM.

      Proposal: remove BOM bytes in the output from TextSource.
