Issues with adding a new font

[Boeing747]

I don't know if this is a problem with the font itself, or with the script, but I've tried literally everything I could to get the FOT-Chiaro Std font (used in Ocarina of Time and Fire Emblem Awakening and Fates) into the game:

module MessageConfig
  FontName        = "FOT-Chiaro Std" #change
  # in Graphics/Windowskins/ (specify empty string to use the default windowskin)
  TextSkinName    = "speech hgss 1"
  ChoiceSkinName  = "choice 1"
  WindowOpacity   = 255
  TextSpeed       = nil # can be positive to wait frames or negative to
                        # show multiple characters in a single frame
  LIGHTTEXTBASE   = Color.new(248,248,248)
  LIGHTTEXTSHADOW = Color.new(72,80,88)
  DARKTEXTBASE    = Color.new(88,88,80)
  DARKTEXTSHADOW  = Color.new(168,184,184)
  # 0 = Pause cursor is displayed at end of text
  # 1 = Pause cursor is displayed at bottom right
  # 2 = Pause cursor is displayed at lower middle side
  CURSORMODE      = 1
  FontSubstitutes = {
     "Power Red and Blue"=>"Pokemon RS",
     "Power Red and Green"=>"Pokemon FireLeaf",
     "Power Green"=>"Pokemon Emerald",
     "Power Green Narrow"=>"Pokemon Emerald Narrow",
     "Power Green Small"=>"Pokemon Emerald Small",
     "Power Clear"=>"Pokemon DP",
     "Power Black and White"=>"Pokemon BW",
     "FOT-Chiaro Std"=>"Fire Emblem"
  }

I don't understand why this isn't working. I've inputted every possible variation on the font's name that might work, I've scoured the Net for solutions, I've converted the OTF file to a TTF file and dropped it into the folder, I've installed the font multiple times, and still the game refuses to recognize it, using Arial in-game instead. Checking the font says that there are no problems with it, so I don't understand why Essentials refuses to use it.

Here's an image of the font:
