Is there a way to add font with subset true to Acroform PDField

Question

I have a pdf with PDTextField, on setting value(Ayşe) with font

PDFont font  = PDType0Font.load(document,new FileInputStream("src/main/resources/fonts/ArialUnicodeMSBold.ttf"), true);

prints gibberish text.

Although with subset as false it works , but increases the file size from 122kb to ~6 MB.

Appreciate your help here.
