Create ttf with a set of chars from other font

Question

Im programming an app that generates PDFs for several situations. In some of them there are greek letters that should be displayed. My Problem is that including a font like arial that provides these chars adds some mb to my pdfs because the whole font is included in the pdf.

Is there a way to include just the chars needed or to generate a "new" font that only includes the chars needed as another font?

Answer 1

The feature you are looking for is font subsetting. This is normally a function of the code making the pdf.
