I sometimes transcribe ancient documents into Word (.docx) files, and as far as possible try to preserve the layout of the originals - eg line and page breaks in the same place. Also for handwritten documents I sometimes use a mixture of fonts to represent different people's handwriting.
When using doPDF to convert the files to pdfs, I find that if I embed the fonts the file size becomes vastly bigger than the original .docx file, so I tend not to embed fonts.
What I would like to know is, if the fonts I used are not available when the pdf file is opened and the pdf reader chooses a substitute, will the layout of my document nevertheless remain exactly the same, or is it liable to change when different fonts are used? While it is not the end of the world for the fonts to be changed, it can matter a lot if the page layout changes.
Please can anyone help with this?
