Uifont not correctly configured?

Best Community,

Hereby my uifont.ali if I remove the bold italic comment tags then reports will not start anymore, otherwise the reports function perfectly.

[PDF:Embed]

# This example shows how to embed Type 1 Arial font into the PDF file:

# Arial = "Arial.pfm Arial.pfb"

# You need to specify the .pfm file before the .pfb file.

# The font files must exist in one of the folders specified in REPORTS_PATH.

[PDF:Subset]

# This example shows how to subset Arial True Type font into the PDF file

Arial....="arial.ttf"

#Arial..Bold..="arialbd.ttf"

#Arial..Italic...="ariali.ttf"

#Arial..Italic.Bold..="arialbi.ttf"
