Encoding a plus (sign) results in a pop-up "Nothing to Convert" - selected text appears to be already encoded.
a "+" sign should convert to %2B

Version URL Plugin 1.1.0.0

url plugin v 1.1.0.0
Copy the string below to a blank notepad doc.

Select the line above

Menu -> Plugins -> URL Plugin > Decode URL

2 seconds and Notepadd++ window and process is terminated.

Same happens for Encode URL.

Notepad++ v8.1.6
URL Plugin v1.1.0.0

Decoding from percent-encoding to text works just fine.

• https://wiki.%E3%83%9D%E3%82%B1%E3%83%A2%E3%83%B3.com/ → decode:
• https://wiki.ポケモン.com/

Encoding results in a string that cannot be decoded. Here, I select just the ポケモン part and press Ctrl+Alt+Shift+E to encode. Alternatively, I select just the ポケモン part and select Plugins → URL Plugin → Encode URL.

• https://wiki.ポケモン.com/ → encode:
• https://wiki.%FFFFFFE3%FFFFFF83%FFFFFF9D%FFFFFFE3%FFFFFF82%FFFFFFB1%FFFFFFE3%FFFFFF83%FFFFFFA2%FFFFFFE3%FFFFFF83%FFFFFFB3.com/

Attempting to decode the above results in a mess.

• https://wiki.%FFFFFFE3%FFFFFF83%FFFFFF9D%FFFFFFE3%FFFFFF82%FFFFFFB1%FFFFFFE3%FFFFFF83%FFFFFFA2%FFFFFFE3%FFFFFF83%FFFFFFB3.com/ → decode:
• https://wiki.ÿFFFFE3ÿFFFF83ÿFFFF9DÿFFFFE3ÿFFFF82ÿFFFFB1ÿFFFFE3ÿFFFF83ÿFFFFA2ÿFFFFE3ÿFFFF83ÿFFFFB3.com/

If I first apply a regex to remove all instances of FFFFFF, decoding can succeed.

• https://wiki.%FFFFFFE3%FFFFFF83%FFFFFF9D%FFFFFFE3%FFFFFF82%FFFFFFB1%FFFFFFE3%FFFFFF83%FFFFFFA2%FFFFFFE3%FFFFFF83%FFFFFFB3.com/ → regex to remove FFFFFF:
• https://wiki.%E3%83%9D%E3%82%B1%E3%83%A2%E3%83%B3.com/ → decode:
• https://wiki.ポケモン.com/

Suggestion:

The encoding feature should not prepend FFFFFF.

Actually, this is a two-part issue, but both parts can be fixed with the same change.

1. When the plugin is used in a portable version of Notepad++ it nevertheless stores its config file in the location of an installed version of Notepad++ (i.e. the user profile of the user currently running Notepad++).
2. The plugin creates the folder for its config file under plugins instead of plugins\config.

I guess both issues can be fixed by using NPPM_GETPLUGINSCONFIGDIR API.

Doesn't work on npp 7.2 (x32). What is the minimum npp version required for a plugin? I get an error that MSVCP140.dll is missing and this popup :

C:\Program Files (x86)\Notepad++\plugins\urlPlugin.dll

Не найден указанный модуль.

urlPlugin.dll is not compatible with the current version of Notepad++.
Do you want to remove this plugin from the plugins directory to prevent this message from the next launch?

urlPlugin 1.2.0 is ABI-incompatible with 64-bit Notepad++ 8.2.1 and older ¹. (I'm unable to test the ARM64 release, but assuming the intptr_t type is 8 bytes long on that ISA, the same concern applies).

Steps to reproduce:

1. Install a portable release of 64-bit Notepad++ 8.2.1
2. Download the appropriate urlPlugin 1.2.0 release and extract to <NPP_DIR>\plugins\urlPlugin
3. Start <NPP_DIR>\notepad++.exe, type and select an encoded URL, e.g.

    https://google.com/search%3Fq%3Dpancakes%20and%20syrup

4. Click the 🔗 toolbar button ("Decode URL")
5. The application crashes

The user manual now includes guidance on how to restrict a plugin to certain Notepad++ version ranges (see esp. n⁰. 7 of the "Rules for adding your plugins into list").

Please consider updating notepad-plus-plus/nppPluginList#432 with compatibility metadata for the affected releases (i.e., at least the x64 version).

I used this a couple of weeks ago and now when I click on it, Notepad_++ shuts down when I try to encode a file. I think there was a NotePad++ installed after the last time this worked successfully about 3 weeks ago.

I'm trying to decode 5 million lines XML file and the plugin does nothing to all text below 7000 lines. Is there any wokaround?
