Does chr() function only support 2 bytes unicode? also Asc().
I am trying to use the updated Material design icon font, which includes more than 6000 icons now, and its code is more than 2 bytes. If use chr(0xF1A29) it doens't work, however if directly copy the character to label.text it works.



B4X: 
Label1.Text = Chr(0xF1A29) 'NO
Label1.Text = "?" 'YES
 
Solution
B4X: 
    Dim fx As JFX
    Dim IconsFont As B4XFont = xui.CreateFont(fx.LoadFont(File.DirAssets,"materialdesignicons-webfont.ttf",64),64)
    Label1.Font = IconsFont
    Label1.Text = UnicodeToString(0xF1A28) & UnicodeToString(0xF1A29) & UnicodeToString(0xF1A2A)
