Japanese Characters are not copied properly

Sakura | Last updated: Jul 13, 2023 01:48AM UTC

Hi. I am trying to create a java burp suite extension using the Montoya API. I needed to copy the selected request and response from the HTTP History to the clipboard. But garbage values were displayed when I paste the values that contain Japanese characters. Sample: Copied using Ctrl+C <title>ページが見つかりませんでした</title> Copied when getting the response from event: <title>ページが見つかりませんでした</title> ------------------------------ I tried the following: 1. property file: pom.xml - added UTF-8 in the <properties><project.build.sourceEncoding> and <build><pluginManagement><plugin><encoding> 2. Java code snippet public List<Component> provideMenuItems(ContextMenuEvent event) { ... HttpRequestResponse requestResponse = event.messageEditorRequestResponse().get().requestResponse(); String response= new String(requestResponse.response().toString().getBytes(), StandardCharsets.UTF_8 ); ... } 3. Burp Suite - User Interface → Inspector and message editor → HTTP message display → Font = MS Gothic Can you tell me how to set the character encoding?

Hi

When converting between Strings and bytes in Burp, data in multi-byte characters can get truncated. It's best to avoid conversion between the two where possible.

Could you try using the following code to generate your response String instead?
String response = new String(requestResponse.response().toByteArray().getBytes(), StandardCharsets.UTF_8);
Please let me know how you get on.
