Some UTF-8 chars are only rendered if there are other UTF-8 chars in the same line

[ST-DDT]

Description of the Issue

Some UTF-8 characters are only rendered if there are other UTF-8 characters in front of them/in the same line.
It does not matter whether there are other normal characters in between

Steps to Reproduce the Issue

Paste the following text in your notepad++

With Prior UTF-8: ✓ ↺
No UTF-8: X ↺
With Suffix UTF-8: ↺ ✓

Expected Behavior

Both/All lines are rendered correctly

Actual Behavior

The line with the ✓ is rendered correctly.
The line without not.
Removing/Adding the symbol changes whether the error occurs.
Repeating ↺ does not fix the issue.

Hello

Settings -> Preferences -> Misc
Turn on the DirectWrite option

Use DirectWrite (May improve rendering special characters, need to restart Notepad++)

I do wonder if there is a reason its not on by default, maybe it doesn't work in certain situations?

Thanks for pointing me to this option. It works very well, but I'll probably forget about this option soon.
Turning it on by default would be nice.

I'll leave this ticket open, in case you wish to use it for tracking the default value change.
Otherwise it can be closed.
