That's the reason why I hate backticks. Hard to read, prone to errors due to keyboard mapping, display fonts etc.. A real pain (in the bash 
). For command substitution I prefer the $(...) construct as shown in scottand and cfajohnsonn's posts.
On top of that I thought they were obsolete...

kbd_mode
KBD_MODE(1) General Commands Manual KBD_MODE(1) NAME
kbd_mode - report or set the keyboard mode SYNOPSIS
kbd_mode [ -a | -u | -k | -s ] [ -C CONSOLE ] DESCRIPTION
Without argument, kbd_mode prints the current keyboard mode (RAW, MEDIUMRAW or XLATE). With argument, it sets the keyboard mode as indi- cated: -s: scancode mode (RAW), -k: keycode mode (MEDIUMRAW), -a: ASCII mode (XLATE), -u: UTF-8 mode (UNICODE). Of course the "-a" is only traditional, and the code used can be any 8-bit character set. With "-u" a 16-bit character set is expected, and these chars are transmitted to the kernel as 1, 2, or 3 bytes (following the UTF-8 coding). In these latter two modes the key mapping defined by loadkeys(1) is used. kbd_mode operates on the console specified by the "-C" option; if there is none, the console associated with stdin is used. Warning: changing the keyboard mode, other than between ASCII and Unicode, will probably make your keyboard unusable. This command is only meant for use (say via remote login) when some program left your keyboard in the wrong state. Note that in some obsolete versions of this program the "-u" option was a synonym for "-s". SEE ALSO
