flowable-ui-idm,task,modeler 三个模块可以正常显示中文，但是flowable-ui-admin中文不能正常显示（flowable6.1.2以下版本包括该版本），比如我们定义了流程之后，显示查询之后，如下图所示：
下面，我们看一下这个bug出现的原因。首先我们看一下上传文档对应的实现，该服务功能位于DeploymentCollectionResource类中的uploadDeployment方法中，实例代码如下：
public DeploymentResponse uploadDeployment(@ApiParam(name = "deploymentKey") @RequestParam(value = "deploymentKey", required = false) String deploymentKey,
@ApiParam(name = "deploymentName") @RequestParam(value = "deploymentName", required = false) String deploymentName,
@ApiParam(name = "tenantId") @RequestParam(value = "tenantId", required = false) String tenantId,
HttpServletRequest request, HttpServletResponse response) {
......
if (StringUtils.isEmpty(deploymentName)) {
}
看到上述的代码StringUtils.isEmpty(deploymentName)就明白了，原来这个地方并没有进行编码工作，中文当然要乱码了，正确的写法，应该是对所有的参数进行解码，类似下面的代码：
URLDecoder.decode(string, "UTF-8")
如果这个问题，让我们自己解决可能有点麻烦，所以直接反馈给flowable官方了，目前官方已经修复了该bug。如下所示：
