Geany won't open syslog - does not look like a text file or the file encoding is not supported.

I'm using Ubuntu 23.04, Gnome 44.0, Geany 1.38.

Occasionally I will copy log files to my $HOME directory to use an editor like geany to look through them.

Any log file should be viewable in Geany, but Geany complains;

syslog does not look like a text file or the file encoding is not supported.

I've uploaded my syslog file to mediafire, to be inspected, as to why this file will not open in geany?

Any file in Linux should work in geany, I've never encountered this problem before on other linux distros.

I have tried all the relevant encoding for english in the preferences and nothing works.

This is my locale;

$ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

Please fix this encoding issue in Ubuntu.

THANKS
