crash when URL-encoding empty parentheses () in UTF-8

[jeichberger]

NPP crashes when trying to URL-encode two parentheses characters in utf-8.

Steps to reproduce:

• create or open a file
• set Encoding to UTF-8
• type empty parentheses () anywhere in the file
• select exactly these parentheses
• click on Plugins -> MIME Tools -> Full URL Encode
• NPP crashes

Environment:

• Windows 11 Enterprise, 22H2
• Notepad++ v8.5.7 (64-bit)
• Mime tools 2.9

Same issue here, though I can't reliably reproduce the crash. Occasionally, NPP crashes after using "URL Encode". Also the crash does not always happen immediately, but on a subsequent action. The following is shown in the Windows Application Log:
