Hello! I need to create cyrillic text in image but all I can get is squares. Here is my code
package main
import (
"github.com/jung-kurt/gofpdf"
"github.com/golang/freetype"
"image"
"fmt"
"os"
"bytes"
"image/jpeg"
"io/ioutil"
"image/draw"
)
func main() {
pwd, err := os.Getwd()
if err != nil {
fmt.Println(err)
os.Exit(1)
}
dataFont, err := ioutil.ReadFile(pwd + "/font/luxisr.ttf")
if err != nil {
fmt.Printf("%v",err)
}
f, err := freetype.ParseFont(dataFont)
if err != nil {
fmt.Printf("%v",err)
}
dst := image.NewRGBA(image.Rect(0, 0, 800, 600))
draw.Draw(dst, dst.Bounds(), image.White, image.ZP, draw.Src)
c := freetype.NewContext()
c.SetDst(dst)
c.SetClip(dst.Bounds())
c.SetSrc(image.Black)
c.SetFont(f)
c.DrawString("русский текст", freetype.Pt(0, 16))
pdf := gofpdf.New("P", "mm", "A4", "")
pdf.AddPage()
buf := new(bytes.Buffer)
err = jpeg.Encode(buf, dst, nil)
if err != nil {
fmt.Printf("%v",err)
}
reader := bytes.NewReader(buf.Bytes())
textName := "text1"
pdf.RegisterImageReader(textName, "jpg", reader)
pdf.Image(textName, 15, 15, 0, 0, false, "jpg", 0, "")
pdf.OutputFileAndClose("test.pdf")
}

Use a different font. The luxisr.ttf
that is bundled wirth freetype
doen't seem to contain a lot of symbols.
If I use your program with a different font (I tried Roboto.ttf
from Google fonts), the cyrillic text renders fine.
Shameless plug: a simple way to locate myfont.ttf
on your system is findfont.Find("myfont.ttf")
from https://github.com/flopp/go-findfont ;)

Yeah, use a different font.
