> WinAnsiEncoding supports not all available characters from the font. That is
> the reason why we moved to the workaround proposed by FAQ, also to use
> PDType0Font. Now we have realized, that returned space width from
> font.getSpaceWidth() returns invalid value.

> try (InputStream fontStream =

> PDDocument document = new PDDocument()) {
> PDFont font = PDType0Font.load(document, fontStream, false);
> assertEquals(20064.0, font.getStringWidth("The quick brown fox
> jumps over the lazy dog."));
> assertEquals(278.0, font.getSpaceWidth()); // FAIL: returns 584.0
