python打印功能中希腊字母的下标问题

Question

我正在尝试为phyiscs项目创建GUI，并且需要这些内容的下标。 H_0， Omega_b， Omega_dm， Omega_\Lambda Omega_r 乳胶

我的代码是这样的

   import PySimpleGUI as sg

sg.change_look_and_feel('Topanga')      

layout = [
    [sg.Text('Enter the Parameters')],
    [sg.Text("H\N{SUBSCRIPT ZERO}", size=(15, 1)), sg.InputText()],
    [sg.Text("\N{GREEK CAPITAL LETTER OMEGA}\N{LATIN SUBSCRIPT SMALL LETTER B}", size=(15, 1)), sg.InputText()],
    [sg.Text("\N{GREEK CAPITAL LETTER OMEGA}\N{LATIN SUBSCRIPT SMALL LETTER R}", size=(15, 1)), sg.InputText()],
    [sg.Text("\N{GREEK CAPITAL LETTER OMEGA}\N{GREEK SUBSCRIPT SMALL LETTER LAMDA}", size=(15, 1)), sg.InputText()],
    [sg.Text("\N{GREEK CAPITAL LETTER OMEGA}\N{LATIN SUBSCRIPT SMALL LETTER DM}", size=(15, 1)), sg.InputText()],
    [sg.Text("z", size=(15, 1)), sg.InputText()],
    [sg.Submit(), sg.Cancel()]
]

window = sg.Window('Simple data entry window', layout)
event, values = window.read()
window.close()
print(event, values[0], values[1], values[2], values[3], values[4], values[5])  

最有趣的是它可以打印诸如M或R之类的字母，但不能打印B？或者它可以打印phi，但不能打印lambda？

您可以尝试此操作，以确保此组合有效。

import PySimpleGUI as sg

sg.change_look_and_feel('Topanga')      

layout = [
    [sg.Text('Enter the Parameters')],
    [sg.Text("H\N{SUBSCRIPT ZERO}", size=(15, 1)), sg.InputText()],
    [sg.Text("\N{GREEK CAPITAL LETTER OMEGA}\N{LATIN SUBSCRIPT SMALL LETTER M}", size=(15, 1)), sg.InputText()],
    [sg.Text("\N{GREEK CAPITAL LETTER OMEGA}\N{LATIN SUBSCRIPT SMALL LETTER R}", size=(15, 1)), sg.InputText()],
    [sg.Text("\N{GREEK CAPITAL LETTER OMEGA}\N{GREEK SUBSCRIPT SMALL LETTER PHI}", size=(15, 1)), sg.InputText()],
    [sg.Text("z", size=(15, 1)), sg.InputText()],
    [sg.Submit(), sg.Cancel()]
]

window = sg.Window('Simple data entry window', layout)
event, values = window.read()
window.close()
print(event, values[0], values[1], values[2], values[3], values[4], values[5])  

请帮助， 谢谢
