How does Notepad++ Manage to display all Characters and Emojis
-
This question is about how Notepad++ is developed. I am doing a test containing these characters for PDF generation:

👩⚕️What I can not understand is how Notepad++ (v7.9.1) displays all these characters perfectly on Windows 10, even when I change the Font Style to Courier New, which lacks these characters if I am not mistaken. I have tried the superman character 🦸♂️ and that one changed into two characters divided by a ZWJ (zero width joiner), so I am sure there is some font or table included in Notepad++ to do this, which lacks the newest emojis. Can you tell me what font it uses or how it is done? I need this to include the font in the PDFs I am generating or replicate the process.

@Martin-Furek said in How does Notepad++ Manage to display all Characters and Emojis:
As far as I know, Notepad++ does not use an internal lookup table for unknown glyphs.
When I look at those characters (including superman) in Courier New, I see:
But if I use my normal Deja Vu Sans Mono font, I get:
Note that the female medical worker splits back to the component woman + medical-symbol, since Deja Vu Sans Mono does not have that glyph.If Notepad++ were using a lookup table to find missing characters, then it would have used the same lookup on woman+medical under Deja Vu Sans Mono as it does with Courier New, but it obviously doesn’t.
Given the number of times in this forum that people have complained about Notepad++ displaying their character as an
□, and we suggest that they use a font that knows that character, and then the character displays correctly for them, I am usually pretty confident in asserting that Notepad++ does not use alternate fonts for characters that don’t have a glyph in the chosen font.On the other hand, some of the emoji you showed use codepoints above U+FFFF, and others use the ZWJ to do the emoji-combo-trick, and I don’t know how the Windows OS and the font system handle such circumstances under the hood. It may be some OS and/or font magic, rather than Notepad++ itself, “helping” you.
And as to your question: how to determine what’s happening behind the scenes and replicate that in generated PDFs: sorry, I don’t think the behind-the-scenes stuff is in Notepad++, so I don’t know how you’d replicate it in your generated PDF.

Should probably note here that what is displayed may also be affected by this setting in the Preferences :
