Possible Fix - Put method name in " " like ClassName["MethodName"].overload......

I forgot the u prefix on a bunch of strings. So now it is trying to format these ASCII strings with Unicode characters, hence it fails. Adding u fixes the issue but makes the Frida script still look funky...

Fixes the "JEB error", but would be better to encode "weird" characters for cleaner Frida scripts.

Jeb4frida.zip
[+] add Auto copy frida functio to clipBoard
[+] removed gen_how_to function (the frida hook was not generated because it didn't have IApkUnit and getMainProject) i working with lots of dump.dex that not have project and its function interfered

Thank you very much for the project, it helps a lot :D

about jadX generates a simple variable reading
example

.method static constructor ()V
.registers 1
00000000 const/16 v0, 18
00000004 new-array v0, v0, [I
00000008 fill-array-data v0, :14
0000000E sput-object v0, A->AMLDZHTU:[I
00000012 return-void

JadX output :
let A = Java.use("o.A");
AMLDZHTU = A.AMLDZHTU.value;
