jar 接收utf-8字符乱码现象
1.今天用php去调用jar出现乱码现象
需要对传递的中文字符进行编码之后再传递这里我用的是urlencode编码，让后java再解码就正常了
这里贴一下代码：
<?php
exec("export LANG='en_US.UTF-8';");
$cmd_str = urlencode("C:\\xampp\\htdocs\\java\\jar\\tetst_for_jacob.doc--安徽理工大学--xxx大学");
$cmd = '"C:\Program Files\Java\jdk1.8.0_181\bin\java.exe" -Dfile.encoding=utf-8 -jar "C:\xampp\htdocs\java\jar\replace_zhixie.jar" "'.$cmd_str.'"';
$res = trim(shell_exec($cmd));
var_dump($res);
