Problem with pasting text/utf8 in DoubleCmd's internal editor

Problem with pasting text/utf8 in DoubleCmd's internal editor.

It is impossible to paste text from Terminology (EFL based terminal emulator, standard in the Enlightenment and Moksha Desktop Environments) - nothing appears/happens in DoubleCmd's internal editor.
Pasting text from Terminology into any other application/editor, eg. Leafpad, works fine.

Terminology version: 1.13.1 but also earlier.
Doublecmd version is 1.1.7.

A similar problem was reported in the past for editor Featherpad https://github.com/tsujan/FeatherPad/issues/699 which was fixed by a change.
Hopefully a similar change can be created for DoubleCmd.

I don't want to assume, but if you're asking about Double Commander, it has an issues forum on github at:
https://github.com/doublecmd/doublecmd/issues

You could ask there or post the bug.

This is indeed in Double Commander, but its internal editor is SynEdit based.

Seem that Terminology does not set correct mime types, I need a list of mimetypes when you try to paste that data.

List of mime types is set by Qt5 widgetset, not by DoubleCmd. Terminology sets the mime type as shown in the https://github.com/tsujan/FeatherPad/issues/699

>>Under X11, Terminology gives text/plain;charset=utf-8 as the MiIME type (or, at least, Qt sees it as such)

I'm having the same issue. When I try to insert math symbols in comments in the Lazarus IDE (version 2.2.6 on Windows 11), things can get a bit tricky.  Check out the screenshot below. The same thing happens when using the TSynEdit component in my app.

Inserting math UTF-8 symbols in the TMemo box (unlike the TSynEdit box) seems to be working fine.  ;)

@LV - it just depends on the font, whether it has glyphs that support the given characters. See attachment

@Paweld, thanks! I've attached a simple test project (Project1.zip). It's got a form with Memo1 and SynEdit1 on it. The Consolas font's used everywhere. I've entered two lines of text, a ∈ A and b ∉ A, and they display fine in the Memo1 field, but not in SynEdit1 or the IDE Lazarus source editor (2024-09-10 174645.png). What am I missing here?
Best regard, LV

Updated: Thanks/Podziękowanie again to Paweld, the problem is sorted!

The problem that was reported originally here still remains.

It works ok here. Lazarus trunk Qt5 on LinuxMint 20.3.

I added Writeln(WStr) here in qt5 file lcl/interfaces/qt5/qtobjects.pas

Code: Pascal  [Select][+][-]
  1.   if (MimeType = 'text/plain') then // do not translate
  2.   begin
  3.     QGuiApplication_platformName(@WStr);
  4.     Writeln('WStr', WStr);
  5.  

it shows 'xcb'.
so I did this small change: added
Code: Pascal  [Select][+][-]
  1. if (WStr = 'xcb') or

here:

Code: Pascal  [Select][+][-]
  1.   //issue #40423
  2.   if (MimeType = 'text/plain') then // do not translate
  3.   begin
  4.     QGuiApplication_platformName(@WStr);
  5.     if (WStr = 'xcb') or (CompareText(Copy(UTF16ToUTF8(WStr), 1, 7),'wayland') = 0) then  // do not translate
  6.     begin
  7.  

then paste works as before (from CudaText to CudaText) and from Terminology to CudaText too!
Zeljko, I don't know what I did. Maybe I added support for MIME type "text/plain;charset=utf8" to X11 too?
But it works now.

You just added wayland platform to execute same code as xcb. WStr should be wayland all the time, so no need to use CompareText()
