Version 2 crashes on openSUSE KDE
I can reproduce this crash in the latest svn by issuing LANG=it texmacs (or any other two-letter code it seems).
LANG=it_IT texmacs seems to work.

Confirmed.

what(): locale::facet::_S_create_c_locale name not valid

But LANG=it_IT texmacs also doesn’t work for me.

Errors remain even when I locale-gen corresponding it_IT.UTF-8 UTF-8.

Thanks for sharing this. Turns out in your case LC_PAPER is the culprit. Doing LC_PAPER=A4 texmacs also crashes. I don’t quite understand how this works, as LC_PAPER isn’t used anywhere in TeXmacs. According to gdb the crash occurs in get_locale_charset, which calls std::locale::global. Perhaps this function doesn’t like certain values of locale environment variables…
LC_PAPER=A4 itself isn’t a valid locale setting. We can check and make sure variables of each of locale categories valid.
https://man7.org/linux/man-pages/man5/locale.5.html
In 2.1.1 too:
LC_PAPER=A4 texmacs
crashes at opening of the welcome document with the errors
Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.
terminate called after throwing an instance of 'std::runtime_error'

If I remember correctly, this is a bug of 2.1.1. Do you have issues with OpenSUSE builds in https://download.opensuse.org/repositories/home:/slowphil:/texmacs-devel/ which are 2.1.2?
Mogan crashes on this as well.
Yes, it crashes too. I will fix it as soon as possible.

Here is the ticket: https://gitee.com/XmacsLabs/mogan/issues/I6SB6F
I will release Mogan v1.1.2 rc5 with this bug fixed as soon as possible.

I found a nice rant on locales. A broken concept, as we experience painfully in TeXmacs. http://www.call-with-current-continuation.org/rants/locale.txt

Here is the fix: https://github.com/XmacsLabs/mogan/pull/557
It takes me about 30 minutes to create the fix.
Mogan v1.1.2 rc5 with the fix is available on Github now.
That is using UTF-8 indifferently, if I understand correctly, thus I am not sure whether it should be like this.
I’m not sure too. I think for Mogan, I can make the decision. But I don’t know why non-UTF 8 is allowed in GNU TeXmacs.
I am not sure whether current environments (such as Windows) are using UTF-8 by default (which should not be the case 30 years ago when TeXmacs was initially programmed). For TeXmacs, I guess it better to use an exception handler to set UTF-8 as fallback.
It’s only by the end of Windows 10 that microsoft made available utf-8 encoding in the OS. So, no, utf-8 is not the default on windows (at least not on all the machines out there). Moreover, AFAIU a program still has a hard time knowing what 8-bit encoding Windows might be using (all the old 8 bit encodings -such as CP-1252- are still available besides utf-8). Actually, unlike other OSes, windows’ code is written for utf-16 (aka wide chars) strings, and for the moment it seems preferable to access it this way.
In practice, TeXmacs’ interface with the OS uses 8-bit (“narrow”) strings, assuming utf-8 encoding. On Windows, a 2-way translation layer adapts between narrow and wide strings (The only portion that escapes this translation is when guile directly accesses OS strings such as environment variables as narrow strings, which can cause issues).
Yes, boost nowide can help solve the problem. And in this case, we have hard coded to UTF-8 on all os except GNU Linux in GNU TeXmacs. I just hard coded it to UTF-8 on GNU/Linux to avoid the crash.
Mogan Editor v1.1.2 is available on OpenSUSE with this bug fixed:
