[BUG] Terminal font not correctly identified using xterm under FreeBSD

[fmc000]

General description of bug:

• Fastfetch shows "Terminal Font: fixed (8.0pt)" when terminal is xterm and OS is FreeBSD 14.1
• What should happen: the font is actually "Liberation Mono 11" in my configuration
• Fastfetch version used: 2.17.2
• Did it work in an older version: I don't know - i just switched from mate-terminal (working) to xterm (not working)
• Where did you get the binary: pkg install fastfetch

Often helpful information:

Screenshot:

The content of the configuration file you use (if any):

{
  "$schema": "https://github.com/fastfetch-cli/fastfetch/raw/dev/doc/json_schema.json",
  "modules": [
    "kernel",
    "packages",
    "de",
    "terminalfont",
    "memory",
    "battery",
    "poweradapter",
  ]
}

OK, I found the bug. In the source, in case of xterm, you look for:

ffParsePropFileHomeValues(".Xresources", 2, (FFpropquery[]) {
{"xterm*faceName:", &fontName},
{"xterm*faceSize:", &fontSize},
});

but .Xresources is somewhat case-insensitive, so I actually had:

XTerm*faceName: Liberation Mono
XTerm*faceSize: 11

and thus fastfetch went for the default, which is:

if (fontName.length == 0)
ffStrbufAppendS(&fontName, "fixed");
if (fontSize.length == 0)
ffStrbufAppendS(&fontSize, "8.0");

I therefore modified my .Xresources to use only lowercase letters and now it's all good.
