Problem description:
Notepad++ is always crashing after calling functionality of Decode JS provided by the plugin. This is probably problem of latest version because this functionality was heavily used before without any problem.

Example text:
U\u017Eivatel m\u00e1 zablokovan\u00fd \u00fa\u010det.


HTMLTag plugin version:
1.1.0.0 (64-bit)

Notepad++ version:
7.7.1 (64-bit)

That's always worked correctly; I presume it’s a problem with the 64-bits version of the plugin. I’ll see what I can find.

Hm... It's not crashing here, with the exact same text. What other plugins have you got installed?

@tinus The bug only happens in Notepad 7.7 onwards. Notepad 7.6.x works fine.
The bug is pretty serious, using the JS Decode option will increase RAM usage exponentially (many gigabytes) in a few seconds (checked with task manager).

Testcase
- In an blank document, type the following string: \u0048\u0065\u006c\u006c\u006f!
- Use the JS Decode option.
- If using version 7.6.x it'll decode to "Hello!". 
- If using version 7.7/7.8 Notepad++ will hang and it'll eat all the RAM until the computer also hangs.

Using Windows 10 LTSC x64, Notepad++ x64 as well. No other plugins other than default.
