geany -V: geany 1.35 (kompiliert am 2019-07-01 mit GTK 3.24.8, GLib 2.60.2) pkg-config --modversion gtk+-3.0: 3.24.10 pkg-config --modversion gtk+-2.0: 2.24.32 uname -r: 5.2.11-arch1-1-ARCH
I try to explain it: In geany the underline is not visible its shown as a space. If you open the same text in an other editor the underline is present. With this bug its impossible to use geany as an editor, especially not as a developement tool.
e.g.: original: BASH_CMDS: a bash_variable geany: BASH CMDS: a bash variable hex-editor: 42 41 53 48 5F 43 4D 44 53 3A 20 61 20 62 61 73 68 5F 76 61 72 69 61 62 6C 65 0A
Kind regards, Walter
