在Linux下通过xxd命令查看文件内容的十六进制:
0000000: 5b 0a 20 20 20 20 7b 0a 20 20 20 20 20 20 20 20 [. {. 0000010: ef bb bf 22 74 69 74 6c 65 22 3a 20 22 22 2c 0a ..."title": "",. 0000020: 20 20 20 20 20 20 20 20 22 70 69 6e 79 69 6e 22 "pinyin" 0000030: 3a 20 22 22 0a 20 20 20 20 7d 0a 5d 0a : "". }.].
开头字节 Charset/encoding EF BB BF UTF-8 FE FF UTF-16/UCS-2, little endian(UTF-16LE) FF FE UTF-16/UCS-2, big endian(UTF-16BE) FF FE 00 00 UTF-32/UCS-4, little endian. 00 00 FE FF UTF-32/UCS-4, big-endia
发现问题解决就很容易了,查找删除BOM就OK了,linux下BOM相关的命令有:
VIM的BOM操作
#添加BOM :set bomb #删除BOM :set nobomb #查询BOM :set bomb?
查找UTF-8编码中的BOM
grep -I -r -l $'\xEF\xBB\xBF' /path
#!/bin/shREPOS="$1" TXN="$2"
SVNLOOK=/usr/bin/svnlook
FILES=`$SVNLOOK changed -t "$TXN" "$REPOS" | awk {'print $2'}`
for FILE in $FILES; do CONTENT=`$SVNLOOK cat -t "$TXN" "$REPOS" "$FILE"`
if echo $CONTENT | head -c 3 | xxd -i | grep -q '0xef, 0xbb, 0xbf'; then echo "BOM!" 1>&2 exit 1 fi done
