@Elayne-T , Do you have your ?-menu’s Debug Info? Do you have plugins in Notepad++ that might be doing something in the background? (Maybe a plugin has popped up a dialog, but because they didn’t code it right, the dialog doesn’t go in fron of Notepad++'s always-in-front.) Do you have a file open that requires Admin privileges to write/save? If so, maybe Windows has popped up the UAC, but it didn’t get to take your full screen like it normally would (the UAC shield icon would be on your taskbar if it’s an issue with the UAC) Do you have anything other than Notepad++ and your browser running? Do you have any applications like AutoHotKey, which assign global hotkeys that maybe it’s interpreting some sequence of keystrokes you are using to Does your browser have any extensions/plugins that might be trying to steal focus away from Notepad++? It will be easier to replicate and find if you give as many details and pieces of relevant information as possible, otherwise something as nebulous an unrepeatable as this is going to be difficult to find. update: one more idea: in the older posts, they mentioned that they’d click in Notepad++ to activate, then after a few seconds of typing, the focus would be lost. Is that the case for you? If so, did you leave the mouse pointer somewhere over the Notepad++ window when you started typing? Or does the mouse pointer start drifting off accidentally (maybe you bumped the mouse while typing, or it gets shaken while you type fervently)? Or does the mouse pointer get moved off intentionally (for example, when I was experimenting with always-on-top, I would move the mouse pointer back over the Chrome window, then use the scrollwheel to scroll the browser tab without clicking in the browser). If your mouse pointer is back to being over the browser (or some third app), maybe something in that other app grabs focus when you leave your mouse lingering over it (I know that some linux GUI will give apps focus whenever the cursor hovers over them, even if they haven’t been clicked to the foreground… maybe some other app – your browser or something else – has given itself such a feature, even on Windows.)

@Coises said: What is really means is, when Notepad++ opens an existing file that contains only ASCII characters, it should treat it as UTF-8 rather than as ANSI. Yeah, so for example: “Treat ASCII-only files as UTF-8 (instead of ANSI)” or something similar could be a more clear wording for the option. Which, for me, raises the question: Why is this only available when UTF-8 is the default encoding for new files? It would add a bit more flexibility to the user, but on the other side it seems very unlikely to set this option if you don’t want UTF-8 as default. So I guess it could be a preventative measure that the user doesn’t set any confusing options.

Search++ version 0.6.2 is available: Fix a critical error that caused ICU searches to crash Notepad++. Fix unwanted characters appearing at the ends of lines in the Results list with Notepad++ rendering mode GDI. Fix regression of line ending symbols being in text color instead of white space color, and switch the CRLF symbol in GDI mode to one that hopefully renders more consistently. Thanks to @guy038 for catching the ICU error and the unwanted characters in the results list in GDI mode. (The ICU error appears to have been due to an uninitialized variable. The faulty code has been there from the beginning. As chance would have it, up until now it just happened to land on memory that contained an innocuous value. Hopefully I didn’t miss anything else similar…)

because it appears those actually return from the enum UniMode, which is enum UniMode {uni8Bit=0, uniUTF8=1, uni16BE=2, uni16LE=3, uniCookie=4, uni7Bit=5, uni16BE_NoBOM=6, uni16LE_NoBOM=7, uniEnd}; according to the source code. In N++ commit 8149f72 in v8.8.8 (Nov 2025), uniCookie has been renamed as uniUTF8_NoBOM inside the N++ source. Thus, I just put in PythonScript Issue #421 to request that there’s a BUFFERENCODING.UTF8_NOBOM, either as replacement or alias of the old meaninglessly-named BUFFERENCODING.COOKIE … I don’t know if it will happen, but at least the request is in. :-)

@ThosRTanner said: This doesn’t seem terribly useful for an installation package though. This is exactly my use case: I download the zip archive end selectively extract only changed files. Some of the files in my installation I explicitly do NOT want to get overwritten. In the end it is really just a matter of taste. And I really appreciate the possibility to choose my desired format. From this I support the current situation, that both format are presented for download.

@guy038 Merci beaucoup!

FYI: Notepad++ v8.9.7 RC2 is available now: https://github.com/donho/notepad-plus-plus/releases/tag/RC2

@rafaello , IANAL, and I don’t own the trademark, but with your clarifications and updates, I believe you’re probably not violating the trademark (IMO). It’s good to see someone who is willing to accept such feedback (rather than digging in your heels for a while, like happened with the aforementioned fork).

@PeterJones Perfect thank you very much!

The Python script I posted is expected to handle single byte errors from UTF8 decoding. Asian languages can be 2 byte for ANSI and so the script may need to get the following byte too to decode both bytes properly. Probably will not find recovery tools and the like that will fix mixed encoding errors as the solution in some cases might be worse then the problem though in this case tested OK. Once saved, then there might be no going back and so creating a backup before the operation would be wise. Inspect the results to confirm is OK.

@rdipardo thank you for pointing that out. I will check and do the needful.

@Sylvester-Bullitt , Release Candidate is available. You probably want to test this version, and report any continued problems with the Open File feature ASAP.

@PeterJones Worked perfectly, thank you.

@Mario-Lemelin , everything work fine except for the equations in latex Not all Markdown processors understand LaTeX. (For example, the Markdown processor for this forum does not.) It appears that MarkdownViewer++ does not have that feature (which doesn’t surprise me). I visited this site (https://github.com/npp-plugins/plugintemplate) but was unablew to find help. That site is just the repository for the C++ template for creating a plugin. It’s not going to have information on how to use any specific plugin. The home for MarkdownViewer++ is https://github.com/nea/MarkdownViewerPlusPlus , so that’s where you’d have to go. But the author has recently set the repo to “read only”, indicating that they are unwilling to support that plugin any more. However, there are other Markdown plugins available from Plugins Admin. I’ve never used them, but two I see include NppMarkdownPanel @ https://github.com/mohzy83/NppMarkdownPanel AnotherMarkdown @ https://github.com/ezyuzin/NppAnotherMarkdown this appears to be a fork of NppMarkdownPanel with a different feature set. when I look at its README, it mentions the ability to use katex for math (I think it’s an option that you’d have to enable by editing a config file for the plugin; you’d want to experiment and read the documentation for that plugin to be sure) – and a quick look at the katex description implies to me that it’s essentially LaTeX compatible syntax. You can install either of those from the Plugins Admin interface. It may be that one of those will do what you need (my bet would be on the second as your best chance).

@blueicehaller , Plugin commands, like Plugins > MIME Tools > URL Encode cannot be recorded in a macro. However, we have a sub-FAQ: “Using Plugin, Run-menu and Macro Commands in Macros” which explains how you can manually edit a recorded macro to include such a command (noting that caveat that if you add or remove plugins, you might have to update your macro to refer to the new menuCmdID for the plugin command).

Thank you again for your help.
