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");
$cmd = '"C:Program FilesJavajdk1.8.0_181injava.exe" -Dfile.encoding=utf-8 -jar "C:xampphtdocsjavajar eplace_zhixie.jar" "'.$cmd_str.'"';

$res = trim(shell_exec($cmd));
var_dump($res);
