iOS Quartz embed font in pdf

Question

I'm trying to generate a PDF page with text that has custom symbols (e.g. "€") using a custom font. I've created a PDF context and page using UIGraphicsBeginPDFContextToData and UIGraphicsBeginPDFPage. My code for rendering text looks something like:

NSString *fontFile = [[NSBundle mainBundle] pathForResource:@"somefont.otf" ofType:nil];
CGDataProviderRef dataProvider = CGDataProviderCreateWithFilename([fontFile cStringUsingEncoding:NSASCIIStringEncoding]);
CGFontRef cgfont = CGFontCreateWithDataProvider(dataProvider);
CTFontRef ctfont = CTFontCreateWithGraphicsFont(cgfont, 10, NULL, NULL);
CFRelease(dataProvider);        

NSString *text = @"Hello €";
int len = [text length];
CGGlyph glyphs[len];
CTFontGetGlyphsForCharacters(ctfont, (const unichar*)[text cStringUsingEncoding:NSUnicodeStringEncoding], glyphs, len);
CGContextSetTextDrawingMode(_context, kCGTextFill);
CGContextShowGlyphsAtPoint(_context, 10, 10, glyphs, len);
CFRelease(cgfont);
CFRelease(ctfont);

Rendering the €-symbol works (because of CTFontGetGlyphsForCharacters), but the font is not embedded in the pdf. Is there any way to do this?

If you use a different font -- does it get embedded in the PDF? Or is it only this particular font that doesn't get embedded? – Terebinthine

I ended up using on of the system fonts 'HelveticaNeue' with witch it works => question remains unanswered. – Epiboly

I have fought with this for quite a while and it turned out that TTF is automagically embedded while OTF is not. Converting my font just worked.

Thanks, this worked for me! This should be chosen as the correct answer. – Pietra
