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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
