由于编辑人员从excel,word等乱七八糟的地方copy内容过来,其中有不可见的字符,导致输出内容看上去是对的,其实是多了一个零长度的字符(比如:\u2028,0000200B ZERO WIDTH SPACE),所以需要过滤掉不合法的unicode编码等特殊字符
整理的正则:
[\\u007f-\\u009f]|\\u00ad|[\\u0483-\\u0489]|[\\u0559-\\u055a]|\\u058a|[\\u0591-\\u05bd]|\\u05bf|[\\u05c1-\\u05c2]|[\\u05c4-\\u05c7]|[\\u0606-\\u060a]|[\\u063b-\\u063f]|\\u0674|[\\u06e5-\\u06e6]|\\u070f|[\\u076e-\\u077f]|\\u0a51|\\u0a75|\\u0b44|[\\u0b62-\\u0b63]|[\\u0c62-\\u0c63]|[\\u0ce2-\\u0ce3]|[\\u0d62-\\u0d63]|\\u135f|[\\u200b-\\u200f]|[\\u2028-\\u202e]|\\u2044|\\u2071|[\\uf701-\\uf70e]|[\\uf710-\\uf71a]|\\ufb1e|[\\ufc5e-\\ufc62]|\\ufeff|\\ufffc
java代码如下:
private String replaceWrongUnicode(String source, String replace) { if (StringUtils.isBlank(source)) { return source; } if (StringUtils.isBlank(replace)) { replace = ""; } Pattern CRLF = Pattern.compile("([\\u007f-\\u009f]|\\u00ad|[\\u0483-\\u0489]|[\\u0559-\\u055a]|\\u058a|[\\u0591-\\u05bd]|\\u05bf|[\\u05c1-\\u05c2]|[\\u05c4-\\u05c7]|[\\u0606-\\u060a]|[\\u063b-\\u063f]|\\u0674|[\\u06e5-\\u06e6]|\\u070f|[\\u076e-\\u077f]|\\u0a51|\\u0a75|\\u0b44|[\\u0b62-\\u0b63]|[\\u0c62-\\u0c63]|[\\u0ce2-\\u0ce3]|[\\u0d62-\\u0d63]|\\u135f|[\\u200b-\\u200f]|[\\u2028-\\u202e]|\\u2044|\\u2071|[\\uf701-\\uf70e]|[\\uf710-\\uf71a]|\\ufb1e|[\\ufc5e-\\ufc62]|\\ufeff|\\ufffc)"); Matcher m = CRLF.matcher(source); if (m.find()) { return m.replaceAll(replace); } return source; }
附:过滤\n成076402276aae5dbec7f672f8f4e5cc81
private String replaceEnter(String source) { if (StringUtils.isBlank(source)) { return source; } Pattern CRLF = Pattern.compile("(\r\n|\r|\n|\n\r)"); Matcher m = CRLF.matcher(source); if (m.find()) { return m.replaceAll("
"); } return source; }
