Error in JD-GUI regarding variable names

Question

When looking at a jar file with JD-GUI I keep getting some sort of display error. It seems to replace variable names/identifiers with the symbol (which in JD-GUI looks like a red snowman, picture attached). Any idea of how to fix this? I tried googling around but wasn't able to describe my situation very well and could therefore not find anyone with the same problem. Thanks in advance!

Answer 1

It looks like the identifier is unicode. You can fix that by using a decompiler like Procyon that escapes unicode. (You should be using Procyon anyway because JD-GUI is a poor decompiler).

Answer 2

Looks like a snow man :). Posting rest of could would help but if you don't want to, use jad and maybe fern flower than compare the two. One should have the "right" naming

Answer 3

该类文件应该已经加密，可以从变量名和方法名中看到，我认为最好的方法是找到一个开源解决方案。
