Removing BOM characters using Java


What needs to happen to a string using Java to be an equivalent of vis

:set nobomb

Assume that BOM comes from the file I am reading.


Solution

  • Java does not handle BOM properly. In fact Java handles a BOM like every other char.

    Found this:

    http://www.rgagnon.com/javadetails/java-handle-utf8-file-with-bom.html

    public static final String UTF8_BOM = "\uFEFF";
    
    private static String removeUTF8BOM(String s) {
        if (s.startsWith(UTF8_BOM)) {
            s = s.substring(1);
        }
        return s;
    }
    

    May be I would use apache IO instead:
