Cannot load font with family rlike /\.\d+$/

[fridrihson]

it is impossible to load font families ending with a dot and numbers (the fontinactive event occurs immediately)

examples:
"Fish_and_Chips_2.0" - failed
"Fish_and_Chips_2.01" - failed
"Fish_and_Chips_2_0" - pass
"Fish_and_Chips_2.0 Regular" - pass
"Fish_and_Chips_2. " - pass
"Fish_and_Chips_2.0 " - pass
