Hi,

can you provide a code example that illustrates the problem?

practically I forced jwt working by changing your code here:
private Font createFont(WFont font) {
/*
if (fontConstructor != null) {
FontMatch fm = trueTypeFonts.matchFont(font);
if (fm.isMatched()) {
try {
FileInputStream fis = new FileInputStream(fm.getFileName());
Font f = (Font)fontConstructor.newInstance(pdf, fis, CodePage.UNICODE, Embed.YES);
f.setSize(font.getSizeLength().toPixels());
return f;
} catch (IllegalArgumentException e) {
logger.error("IllegalArgumentException while creating font {}", font.getCssText(), e);
} catch (InstantiationException e) {
logger.error("InstantiationException while creating font {}", font.getCssText(), e);
} catch (IllegalAccessException e) {
logger.error("IllegalAccessException while creating font {}", font.getCssText(), e);
} catch (InvocationTargetException e) {
logger.error("InvocationTargetException while creating font {}", font.getCssText(), e);
} catch (FileNotFoundException e) {
logger.info("FileNotFoundException while creating font {}", font.getCssText(), e);
}
}
}
*/
FontMatch fm = trueTypeFonts.matchFont(font);
if (fm.isMatched()) {
try {
FileInputStream fis = new FileInputStream(fm.getFileName());
Font f = new Font(pdf, fis, Font.STREAM);
f.setSize(font.getSizeLength().toPixels());
return f;
} catch (Exception e) {
logger.info("Exception while creating font {}", font.getCssText(), e);
}
}

    String name = PdfUtils.toBase14Font(font);
    try {
        Font f = new Font(pdf, name);
        f.setSize(font.getSizeLength().toPixels());
        return f;
    } catch (Exception e) {
        logger.info("Error creating font {}", font.getCssText(), e);
        return null;
    }
}

btw, added code to split long strings w/o whitespace, e.g. urls
@Override
public WTextItem measureText(CharSequence text, double maxWidth, boolean wordWrap) {
processChangeFlags();

    if (wordWrap) {
        if (maxWidth == -1) {
            return new WTextItem(text, font.stringWidth(text.toString()));
        } else {
            String previousWord = null;
            double previousWordWidth = 0;

            int len = text.length();            
            for (int i = 0; i < len; ++i) {
                double w;
                if (Character.isWhitespace(text.charAt(i)))
                    w = font.stringWidth(text.subSequence(0, i).toString());
                else if (i == len - 1)
                    w = font.stringWidth(text.subSequence(0, i + 1).toString());
                else
                    continue;

                String s = text.subSequence(0, i + 1).toString();

                if (w > maxWidth) {
                    if (previousWord == null)
                        return measureTextExact(text, maxWidth);
                        /*return new WTextItem(s, w);*/
                    else
                        return new WTextItem(previousWord, previousWordWidth);
                } else {
                    previousWord = s;
                    previousWordWidth = w;
                }
            }
            return new WTextItem(text, font.stringWidth(text.toString()));
        }
    } else {
        return new WTextItem(text, font.stringWidth(text.toString()));
    }
}

private WTextItem measureTextExact(CharSequence text, double maxWidth) {
    int len = text.length();            
    double width = 0;
    for (int i = 0; i < len; ++i) {
        double w = font.stringWidth(text.subSequence(0, i + 1).toString());
        if (w > maxWidth)
            return new WTextItem(text.subSequence(0, i).toString(), width);
        width = w;
    }
    return new WTextItem(text, width);
}

Problem finally - that default font is chosen, which has no cyrillic chars, and pdf is garbage there.

I believe this is a limitation of the open source version of PDFJet. I think it simply does not support font embedding.

maybe, but

1. Trial version from PDFJet site does not contain 4-args constructor.
2. I believe font matching and font embedding are different features.

Yeah, things may have changed in the meantime. I think you still needed the font embedding feature (or just TTF font support) in PDFJet in order to actually do proper font matching, which was not in the open source version.
