Android Question Changing the system font shows Material Icons label with Chinese-like chars

[Alessandro71]

I need to create a label by code, by cloning an existing label, which uses Material Icons font.
Here is how it looks: the grey icon is the original label, while the red one is the clone

if I set the system font to anything else than the default (SamsungOne in this example)

the cloned icon font changes to a strange font

proof-of-concept project is attached.

Test Clone

    Dim new As B4XView = CloneLabelToB4XView(Label1)
    Log(new.Font)
    Log(new.Text)

Public Sub CloneLabelToB4XView(lbl As Label) As B4XView
    Dim new As B4XView = lbl
    new.Text = lbl.Text
    new.Font = xui.CreateFont(lbl.Font, lbl.Font.Size)
    new.TextColor = xui.Color_Red
    Return new
End Sub
