> 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|https://www.google.com/url?q=http://www.unicode.org/versions/Unicode5.0.0/ch02.pdf&sa=D&usg=AFQjCNF_PW0McUUnM1UrvZSIwgvAj1uUKw]):
> "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|https://www.google.com/url?q=https://bugs.java.com/bugdatabase/view_bug.do?bug_id%3D4508058&sa=D&usg=AFQjCNEdT7vUK99N5bxQc9fkCt-uIG2v7Q]).
> As a general practice, it's suggested to use UTF-8 without BOM.
> Proposal: remove BOM bytes in the output from TextSource.
