wxExecute: Unicode arguments on Linux, how to?

What must I do to be able to execute a program with a path containing unicode characters as argument?
The following will fail:
Code: Select all
wxString cmd = wxString::Format("\"%s\" \"%s\"", "/usr/bin/program", "/home/me/Skæg.ext");
wxExecute(cmd, wxEXEC_ASYNC | wxEXEC_MAKE_GROUP_LEADER, m_Process);
But if I rename the argument to "Skaeg.ext" and use that as argument there are no problems.

have you tried using the %S or %ls format specifiers?

The formatters are not part of the problem. This example does not work on Linux (works fine on Windows, though):
Code: Select all
wxString cmd = "/usr/bin/program";
cmd += " \"/home/me/Skæg.ext\"";
wxExecute(cmd, wxEXEC_ASYNC | wxEXEC_MAKE_GROUP_LEADER, m_Process);
P.S: Executing the command in a terminal (on Linux) works fine.
P.P.S: Same problem:

AFAIK Linux uses UTF-8 on the command line. Trace into the wxExecute call and see what it does.

It converts the command line into char** and executes the command using "execvp":
https://linux.die.net/man/3/execvp I cannot spot the issue, though. The program returns error "file not found", so I assume it is a bug in wxWidgets 3.0.2.

The code you posted is from the latest master which is significantly different from the one in 3.0.2.
So which wxWidgets version are you using? And if you're using 3.0.2, can you try again with the latest development version?

I have tried to upgrade wx to 3.1.0 and it seems to have solved the issue

I've had some more time to test this issue and wx version 3.1 has fixed the issue, marking as solved
