<![CDATA[Missing or wrong Unicode characters for Japanese Katakana]]>There are some missing or wrong Japanese Katakana letters in unicode font.

The sample code below shows the unexpected results.

from m5stack import *
from m5stack_ui import *
from uiflow import *
import time

screen = M5Screen()
screen.clean_screen()
screen.set_screen_bg_color(0xFFFFFF)

label0 = M5Label('テストケース', x=91, y=108, color=0x000, font=FONT_UNICODE_24, parent=None)

label0.set_text_font(FONT_UNICODE_24)
label0.set_text(str('テストケース'))
wait(5)
label0.set_text('ミドル・ドット')
  1. テストケース => テストケス" ["ー" (0x30FC; Katakana-Hiragana Prolonged Sound Mark) is missing ]
  2. ミドル・ドット => ミドル勹ドット ["・" (0x30FB; Katakana Middle Dot) is replaced with a wrong character (some character like "勹" but a bit different)]

Without these two characters("ー" and "・"), we have extreme difficulty in using Japanese text in a label.

Here lists my environment.

  • Device: M5Stack core2
  • firmware: v1.8.1 (via M5Burner)
  • UIFlow: v1.8.1

So this is the problem occurs only on core2.
v1.8.3 for core2 still has this problem, and I strongly wish It would soon be fixed.
