Emgu-CV-4.5.3 : Freetype2 class dont show correctly utf8 text

, , ,
3

can reproduce this.

probably a bug in how opencv uses the results from freetype.

you should open an issue on opencv’s github about this.

#!/usr/bin/env python3
import numpy as np
import cv2 as cv

ft = cv.freetype.createFreeType2()
#ft.loadFontData(R"C:\Windows\Fonts\Tahoma.ttf", 0)
ft.loadFontData(R"C:\Windows\Fonts\Calibri.ttf", 0)

canvas = np.empty((400, 600, 3), np.uint8)
canvas[:] = (179, 222, 245)

text = "سلام = HI"
text = "\u0633\u0644\u0627\u0645 = HI"

ft.putText(
	img=canvas,
	text=text,
	org=(100, 200),
	fontHeight=100,
	color=(0, 0, 255),
	thickness=cv.FILLED,
	line_type=cv.LINE_AA,
	bottomLeftOrigin=True
)

cv.imshow("canvas", canvas)
cv.waitKey()
cv.destroyAllWindows()
