This differs from WordвЂ™s UI, which tends to auto select the EOP character if you navigate next to it. We decided to match the Visual-Studio UI for selecting and not selecting the EOP character at the end of a line. The tricks came in dealing with deleting or replacing the first line and in scrolling the display correctly with a nonzero document-space-before value. The space-before value is included in the ascent of the first line in the document. Since RichEdit is a rich-text editor, it supports these properties, and it was natural to implement the drop-down space as вЂњdocument space beforeвЂќ. In rich-text formatting, the paragraph space-before and space-after properties are used to add spacing between paragraphs. It was a bit tricky to get RichEdit to provide the associated functionality. In case the dialog overlaps the starting text, the user can drag the text down just under the bottom of the dialog.

Visual Studio Code has a nifty Find/Replace dialog that drops down into the upper right of the text area. For example, the new mode displays the family emoji ZWJ sequenceрџ‘ЁвЂЌвќ¤пёЏвЂЌрџ‘©given by the codes U+1F468 ZWJ U+2764 U+FE0F ZWJ U+1F469 as This lets you figure out how a ZWJ sequence is constructed. You can navigate inside the ZWJ sequence using the в†ђ and в†’ keys and type Alt+x to see the codes of the characters comprising the ZWJ sequence. In the new Notepad вЂњShow Unicode control charactersвЂќ mode, ZWJ sequences are broken apart at the ZWJвЂ™s and the ZWJвЂ™s are displayed by the ZWJ zero-width glyph. And classic Notepad doesnвЂ™t display ZWJ sequences and emoji in general in color. But inside emoji ZWJ sequences, such as family emojis, the mode doesnвЂ™t break the sequence apart at the ZWJвЂ™s and doesnвЂ™t reveal the ZWJвЂ™s by the zero-width ZWJ glyph. It also displays the zero-width joiner (ZWJ-U+200D) with a вЂњzero-widthвЂќ vertical line topped by an x. This is very valuable, for example, in revealing the Bidi RLO (U+202E) and LRO (U+202D) codes that override the usual character directionalities and are sometimes used to spoof files for nefarious purposes. This mode displays Bidi zero-width control characters using distinctive вЂњzero-widthвЂќ glyphs. Notepad has had a вЂњShow Unicode control charactersвЂќ option in its context menu for many years. Show Unicode control characters mode and emoji This is still the case, but you can tell RichEdit to recognize the kind of line termination in a file and use that choice for saving/copying the file by sending the EM_SETENDOFLINE message with wparam = EC_ENDOFLINE_DETECTFROMCONTENT.

Internally RichEdit follows the lead of Word and the Mac in terminating paragraphs with a CR and converting LFвЂ™s and CRLFвЂ™s to CR when reading in a file or storing text via an API like WM_SETTEXT or ITextRange2::SetText2. So, a file with LF- terminated lines remains LF terminated and displayed correctly. To fix this problem, Notepad went one better: it checked to see which line ending came first and then made that line ending the default for the file.

I used to open the Unicode Character Data files, which contain LF-terminated lines, with WordPad and save them to convert the LFвЂ™s to CRLFвЂ™s so that Notepad would display them correctly. For years Notepad didnвЂ™t break Unix-convention lines that terminated with a LF (U+000A) instead of a CRLF (U+000D U+000A). The classic Notepad has two handy features that werenвЂ™t implemented in RichEdit: line-ending detection (CR, LF, CRLF) and the вЂњShow Unicode control charactersвЂќ mode (discussed next). This post describes some additions and implementation details. Accordingly, itвЂ™s taken significant effort to use RichEdit as the new NotepadвЂ™s editing engine. And classic Notepad has been improved in various ways, such as better performance, line-ending detection (CR, LF, CRLF), and a вЂњShow Unicode control charactersвЂќ context-menu option. Notepad is often used to view large files, so high performance is important, and lines can be crazy long. But those plain-text controls have been small and typically exist in dialog boxes. RichEdit has had plain-text controls ever since Office 97 (last century!) and theyвЂ™ve been used myriad times. You might guess that using a RichEdit plain-text control in Notepad would be a slam dunk.

In addition to a Windows 11 look with rounded corners and a dark-theme option, the new Notepad includes several standard RichEdit editing enhancements, such as Alt+x for entering Unicode characters, Ctrl+} for toggling between matching brackets/parentheses, multilevel undo, drag & drop, color emoji, and autoURL detection. The new Windows 11 Notepad uses RichEdit and runs on up-to-date Windows 11 installations.
