如何更改 Kivy 字符串中某些字符的偏移量？

Question

How can I set offset for a some characters or words in Kivy? I'd like to obtain something like

It consists of 24pt Windings symbol which has offset -18% (to have bigger sign vertically centered relatively smaller font) and 12 pt common font label. It's important to have symbol with the text inline, 'cause really it's the part of a text paragraph. I've tried to do something like

string = "[sub][size=45]t[/size][/sub]est"

But to no avail - Kivy just ignores all previous [] markup commands, ie if I use [sub] and [size=...] it always use the last instruction to the basic text, so I cannot have BOTH [sub] and [size=...] rendered. I know that I can install pango library, fully reinstall Kivy and then I can achieve what I need with [font_features]. The problem is that I will build Android app from this code so I need to keep app as light as possible (it is 30M right now already and starts relatively slowly even at middle-level smartphones). Moreover, it's quite unobviously how can I add pango library to buildozer and build APK with pango support (and how to turn ON pango text render under Android).

If you are using this string in a Label , you can also use the font_size attribute of the Label . Perhaps you could use that attribute to set the size for the entire Label to the size that you want inside the [sub] and [/sub] , and use markup to adjust the rest of the string. Like this:

    t = "[sub]t[/sub][size=12]est[/size]"
    l = Label(text=t, font_size=45, markup=True)
