Doesn't support Chinese characters

[Paul]

For example: invoice generate --from "你好"

@paulrouget I got it working by modding the source to use a different font that supports UTF8. You can get the font (NotoSansSC-Regular.ttf) at https://github.com/jsntn/webfonts/ and put it in the same directory as pdf.go

diff --git a/pdf.go b/pdf.go
index 5a1cd55..b10a2e9 100644
--- a/pdf.go
+++ b/pdf.go

        pdf.SetTextColor(0, 0, 0)
        _ = pdf.Cell(nil, title)

go build

./invoice generate --title "中文，你好！" && xdg-open invoice.pdf

It will be up to @maaslalani to decide what font to use/include/distribute though.
