DejuVu font does not contain Chinese or Thai characters - affects Fan Chart and PDF reports

melizaa commented 6 years ago

I see Thai name for instance in Wife Duangruthai Janmo ‘Jo’ ดวงฤทย จนทรโม ‘โจ’ in pdf reports as boxes in pdf reports. 2017-11-16_13-29-46

PDF reports use the DejaVu sans font, which does not currently contain Thai letters.

See the section on coverage in https://en.wikipedia.org/wiki/DejaVu_fonts

fisharebest commented 6 years ago

Noto sans offers wider coverage - but not in a single .ttf file.

We could attempt to merge various noto files, but there are limits such as the maximum number of glyphs in a file, and different line-heights, etc. for different scripts. More info at https://github.com/googlei18n/noto-fonts/issues/13

Also, noto was designed for screen use (i.e. android phones), rather than print and PDF is aimed at print media.

In the above linked issue they mention that Ariel unicode MS has all charts in 1 font file. Why not use that?

fisharebest commented 6 years ago

Arial is a proprietory font, owned by Microsoft.

We are not allowed to include it in an open-source project. See https://en.wikipedia.org/wiki/Arial#Distribution

You might try this one: https://github.com/klokantech/klokantech-gl-fonts

@fisharebest How are the pdf's created? Can this be changed to use multiple fonts with e.g. fontconfig? Especially as the dejavu-project seems to be not taken care of anymore.

Not only Chinese and Thai languages print undefined characters or undefined offsets in PDF and HTML reports. I look now at a Family report in different webtrees languages.

@melizaa The Chinese characters in the PDF report are not displayed. Have you solved this problem? I uploaded several font files and modified the file name, but still failed.

iyoua commented 2 years ago

I downloaded a font and copied it to tcpdf\fonts folder. After modifying the report code, the body of the report is displayed in Chinese, but the report header is always not displayed. I can't find the reason. Even if I change the style to the style of the body, it won't work. Why? `
