Description of the Issue

Steps to Reproduce the Issue

  1. Paste the following text into a blank document in Notepad++
☞
☞☛

Expected Behavior

In the first line, a WHITE RIGHT POINTING INDEX glyph is displayed, for the Unicode character U+261E
In the second line, the same glyph is displayed, followed by a BLACK RIGHT POINTING INDEX (U+261B)

Actual Behavior

In the first line, an empty square is rendered.
The second line is properly displayed. In fact, if a U+261B is appended to any sequence of U+261E, then all of them are rendered correctly; if the former is removed again, then the empty squares appear again.

Debug Information

Notepad++ v7.5.6 (32-bit)
Build time : Mar 19 2018 - 00:26:59
Path : C:\Program Files (x86)\Notepad++\notepad++.exe
Admin mode : OFF
Local Conf mode : OFF
OS : Windows 10 (64-bit)
Plugins : DSpellCheck.dll mimeTools.dll NppConverter.dll NppExport.dll

More info

Default font is Courier New
I guess this issue is not constrained to those characters, but it may be a symptom of a wider issue with higher-block Unicode characters.

Don't have reported behavior, anything you see that is different to your setup other than OS?
I don't expect the local conf mode or using a zip being the culprit - but maybe worth testing it.

Duplicate of #870, #813, #4086, #4056, #675, #1621, #3458 may be many more.

BTW, npp is text editor. Why do we need special characters in it?

please update your notepad++ to the latest version Notepad++ 7.6.6 and migrate or reinstall your plugins if you update from version 7.5.9 or below.
if your issue still persists, and it is still of relevance, please feel free to file a new issue as easy to understand and reproducible as possible.

thank you for your help and best regards.

... by using Scintilla's DirectWrite technology.
It allows ligature support if the font needed (for exemple "Fira Code") is installed.
