@Gaaaz follow these steps:

WORKAROUND

1. Use Chrome
2. Go to 192.168.1.1 (your router ip)
3. Login and then go to Advanced -> SMS -> Inbox
4. Press F12 or open Developer Toolbars
5. Go to Sources Panel
6. On the right check the "Pause on caught exception" 
7. Click on "↻ Refresh" link
8. Now press F8 until a file called VMXXX (where X is a number) opens (The file start with var CryptoJS = CryptoJS)
9. Click on the { } icon in bottom left to prettify the code 
10. If the line selected is near   return decodeURIComponent(escape(a.stringify(t))) then in the console write:

11. this.stringify = function(t){ try{return a.stringify(t)} catch(t){console.log(t)}}

12. Press Enter
13. Uncheck the "Pause on caught exception"
14. Press F8 
15. Click again on the "↻ Refresh" link, now you should see the sms

@Chalda 

Thank you very much for your help

I tried but nothing to do !!

at the level of F8 I do not find VMXXX ?

I find: decodeURIComponent in a folder called:

             encrypt.js

I have this line:

if (result + = tempresult,
         result = result.replace (/ \ 0 * $ / g, ""),
         ! encrypt) {
             if (1 === padding) {
                 var paddingChars = 0;
                 (len = result.length) && (paddingChars = result.charCodeAt (len - 1)),
                 paddingChars <= 8 && (result = result.substring (0, len - paddingChars))
             }
             result = decodeURIComponent (escape (result))
         }
         return result
     }

I still tried to enter this command

this.stringify = function(t){ try{return a.stringify(t)} catch(t){console.log(t)}}

in the console but nothing happens !!
I can't read the SMS

I can't find the term: stringify?

an idea ?

Thank you

@Gaaaz 

Press "Resume script execution" (|▶) until you see this:

Thent continue from step 9

@Chalda 

Really a huge thank you !!

I was doing a wrong manipulation at this stage 6 :
I did not check : "Pause on caught exception"

Sorry for the inconvenience .....

Everything is perfect and in fact very simple !!
I could read the SMS

Again, thank you very much !!

@Chalda 

Good afternoon,

I have the same problem. I have the latest beta version, (1.1.0 0.9.1 v0001.0 Build 200320 Rel.62159n), I am trying to follow the steps but I get stuck in step 8. Sometimes I show the VMXXX file and other times not. I don't see "var CryptoJS = CryptoJS)". Could you put screenshots of the steps? I would be very grateful. Thanks a lot.

@Kevin_Z 

After about one week testing, it works for me!!!

I can read all new incomming sms (with chinese character) and keep in router.

Much thanks Kevin_Z  

@Kevin_Z 

Good Morning. I have the same problem, I cannot read the received sms. I have installed the latest beta version and it doesn't work. Thank you.
