X3.5手机端，发帖上传附件（例如PDF、MP3）显示问号，无法正常上传附件。上传图片则正常 New
X3.5手机端，发帖上传附件。上传PDF，和MP3，插入后，都会显示❓️问号但手机浏览器切换到桌面版的编辑器，进行上传，就没有任何问题。仅仅只有在手机版中，上传附件是这样的。上传图片则是很正常。怎么才可以解决这个问题呢？我的版本是X3.5
手机端编辑器，上传附件，无论是什么文件格式。上传都是显示问号
发布后，前端显示，也是问号，附件无法正常显示，也无法正常下载

你看下，你传的文件是不是中文开头的，且只包含中文或一些特殊符号（包括括号引号只能是正常英文和数字的）

浏览器：手机VIVO浏览器，手机Edge浏览器，手机Chrome浏览器，都一样会这样的情况
复现步骤：手机浏览器，发帖/编辑帖子，点击【上传附件】按钮，选择MP3文件或PDF文件（其他格式暂未尝试过）

我上传的PDF体积比图片还小，图片上传正常，但PDF就不行。应该是只要是手机端的编辑器，上传附件就不行。但转到桌面版的编辑器上传附件就没有问题
