> Issue Type: Bug
> Components: AcroForm, PDModel
> Affects Versions: 2.0.12, 2.0.13, 2.0.14, 2.0.15, 2.0.16
> Reporter: André Hertwig

> Hi
> I have a PDF form and want to add additional fonts, because the default fonts does not allow cyrillic or greek chars for example.
> I add the font as following (LiberationSans-Regular):
> {code}
> PDResources formResources = acroForm.getDefaultResources();
> try (InputStream defaultTTFont1 = new FileInputStream(myFontFile)){
>
> PDFont font2 = PDType0Font.load(pdfDocument, defaultTTFont1, true);
> COSName fontName = formResources.add(font2);
> }
> acroForm.setDefaultResources(formResources);
> {code}
> I debugged it, the valiable ttf is set.
> When filling a text field with for example cyrillic letters an exception occurs, than I change the defaultAppereance of that field using the initially added font.
> But the original TTF will not really used, instead there wil be created new font classes with a TTF of null, so it seems to be impossible to use a different TTF.
> Furthermore the font will not be embedded in the resulting PDF.
> {code}
> PDCIDFontType2.<init>(COSDictionary, PDType0Font, TrueTypeFont) line: 75 <- initialized with TrueTypeFont = null
> PDCIDFontType2.<init>(COSDictionary, PDType0Font) line: 62
> PDFontFactory.createDescendantFont(COSDictionary, PDType0Font) line: 139
> PDType0Font.<init>(COSDictionary) line: 192
> PDFontFactory.createFont(COSDictionary, ResourceCache) line: 97
> PDResources.getFont(COSName) line: 146
> PDDefaultAppearanceString.processSetFont(List<COSBase>) line: 173
> PDDefaultAppearanceString.processOperator(Operator, List<COSBase>) line: 132
> PDDefaultAppearanceString.processAppearanceStringOperators(byte[]) line: 108
> PDDefaultAppearanceString.<init>(COSString, PDResources) line: 86
> PDTextField(PDVariableText).getDefaultAppearanceString() line: 93
> AppearanceGeneratorHelper.<init>(PDVariableText) line: 100
> PDTextField.constructAppearances() line: 263
> PDTextField(PDTerminalField).applyChange() line: 228
> PDTextField.setValue(String) line: 219
> {code}
> As a result of this behavoir I get the following warning:
> {code}
> WARN org.apache.pdfbox.pdmodel.font.PDCIDFontType2 - Using fallback font LiberationSans for CID-keyed TrueType font LiberationSans-Regular
> {code}
> When opening the PDF afterwards, I will get an error from AcrobatReader, that the font "LiberationSans-Regular" could be found, because the font is not embedded... like my own fonts..
> I tried it back to version 2.0.12 - always the same behavior.
