@davidi67 , But did you do the suggested fix for that, before uninstalling and installing an older unsupported version to see if that would work. Since the original poster never responded here, it’s unclear if that fixed the problem, and your not trying to use the fix, amounts to the same lack of knowledge this issue still presents. I haven’t had any problems so it doesn’t affect me, but others having the same issue might like to hear that you tried the fix and it worked or not, so they have a better idea of what to look for if that does or doesn’t fix it.

@Troglo37 Well, they already have a “auto-backup” feature, it just doesn’t target config files, only files you open in the editor and when you make changes to that file and haven’t closed it. I made my own program to just copy files, but I’m not ready to look at doing something that checks every possible setting for a comparison against original or recently changed config files that may have had only minor changes. I think that’s why something like this hasn’t been done yet. So many settings, AND between versions, the menu and the options may change as well, so if someone wrote such a program/plugin/feature, it would have to be constantly updated for when the Notepad++ program changes, as well.

@PeterJones i just wont bother using notepad++ again, ill go find a better alternative

Hello, @coises and All, Thank you very much, @coises, for your valuable advice ! As I already used a user definitions file, named Definitions.json5, containing the main examples from the documentation : Before starting N++, I simply included your modified implicit combining rules section to the definitions.json5 file, described below : { // A user definitions file is a JSONC file containing pairs of keys and values // listing what you type after the Compose key and what Compose types in response. // Each pair except the last must be followed by a comma. // Two forward slashes begin a comment: Compose for Notepad++ ignores // the slashes and everything after them on the same line. // You can use the standard escapes \n (new line), \r (return), \t (tab), // \" (quote within a quoted string) and \\ (backslash within a quoted string). // You can also use Unicode escapes, \u followed by four hexadecimal digits, // for example: "\u20ac" for "€", the Euro sign. Escape sequences for characters // outside the basic multilingual plane (code points 0x10000 or greater) // can only be entered as a UTF-16 surrogate pair. // You should save this file with a .jsonc extension. // Compose for Notepad++ reads the file each time you launch Notepad++, // so be sure to save it in a place where it won't be disturbed. "implicit combining rules" : { "'" : ["\u0301", "\u030B", true , "\u0317"], // acute accent | double | same as plain | acute accent below ")" : ["\u0306", false , true , "\u032E"], // breve | - | same as plain | breve below ">" : ["\u030C", false , true , "\u032C"], // caron/hacek | - | same as plain | caron/hacek below "," : ["\u0327", false , "\u0313", "\u0326"], // cedilla | - | comma above | comma below "ç" : ["\u0302", false , true , "\u032D"], // circumflex | - | same as plain | circumflex below "\"": ["\u0308", false , true , "\u0324"], // diaeresis | - | same as plain | diaeresis below "." : ["\u0307", false , true , "\u0323"], // dot above | - | same as plain | dot below "è" : ["\u0300", "\u030F", true , "\u0316"], // grave accent | double | same as plain | grave accent below "?" : ["\u0309", false , true , false ], // hook above | - | same as plain | - "+" : ["\u031B", false , true , false ], // horn | - | same as plain | - "-" : ["\u0304", false , true , "\u0331"], // macron | - | same as plain | macron below ";" : ["\u0328", false , "\u1DCE", true ], // ogonek | - | ogonnek above | same as plain "*" : ["\u030A", false , true , "\u0325"], // ring above | - | same as plain | ring below "é" : ["\u0303", false , true , "\u0330"], // tilde | - | same as plain | tilde below "_" : ["\u0332", "\u0333", "\u0305", true ] // underline | double | overline | same as plain }, "CC" : "\u2102", // double-struck capital C "rx" : "℞", // prescription symbol "dia" : "💎", // diamond symbol "br" : "Best Regards,\r\n\r\nguy038\r\n" // End of Post } Then, I started N++. To be sure that this json file was correct : I ran the Plugins > Compose > User definitions file... option. I clicked on the Select button. => No error occured ;-) And, indeed, no need to use the |Alt Gr] key and the [SP] key anymore, within the implicit combining rules section, on my French keyboard ! So, I also updated the main_Compose.txt file, in my Google drive account, which can be downloaded from the same address as before. Best Regards, guy038
