[Spire.PDF for Android] Use device font

[RicoScheller]

Hi

I'm trying to create a PDF on Android using Spire.PDF for Android via Java 4.1.0.
The problem I'm having is:

If I use

Code: Select all

private static final PdfFontBase font = new PdfFont(PdfFontFamily.Helvetica, 10);

then UTF-8 characters are not correctly displayed in the resulting PDF. (For example the German word "Änderung")

If I use

Code: Select all

private static final PdfFontBase font = new PdfTrueTypeFont("Arial", 10);

(like for .Net), it obviously doesn't work because Android doesn't have an Arial Font.

Based on this SO-question/answer https://stackoverflow.com/questions/39535475/what-is-the-default-font-family-in-android I also tried

Code: Select all

 private static final PdfFontBase font = new PdfTrueTypeFont("sans-serif", 10);

and

Code: Select all

private static final PdfFontBase font = new PdfTrueTypeFont("Roboto", 10);

which doesn't work.

PdfCjkStandardFonts work, but they don't look good for normal text.

So how can I display UTF-8 characters correctly?
And yes, I probably could bundle some font file with my app and embed this. But delivering fonts with your app is legally very complicated so I'd like to not do that.

Ok, while creating a sample project, I realized that using "PdfFontFamily.Helvetica" in Spire.PDF for Android 4.1.0 leads to wrongly displayed UTF-8 characters, but the same works in version 8.8.1.

So, even though the release notes https://www.e-iceblue.com/news/spire-pdf-java/Spire.PDF-for-Android-via-Java-8.8.1-enhances-the-conversion-from-PDF-to-DOCX.html say nothing about this, upgrading to version 8.8.1 fixed the issue.
