'x' character is replaced by multplication in TextBlock.Text (Avalonia 11.1.4)

[Kruno313]

Describe the bug

I format my values as hexadecimal (with "0x" preamble) and output them on TextBlock.
I noticed that the x is replaced with an higher placed x, so "0x1A30" looks like multiplication operation. It is done only when x is between numbers.
It looks strange and it's wrong.

To Reproduce

<TextBlock Text="0x1234" />

It is obvious in designer.

Expected behavior

TextBlock should not change text. Searching and replacing makes it only slover for no benefit, making only problems.

Avalonia version

11.1.4

OS

Windows

This is just regular text shaping. Use a different font or disable the font feature.

No, it is not. Text like "x0x23" has first x normal and second x changed.
I searched unicode table and found cyrilic x, 525 i think. Looks same as latin x. That is not changed.

It was not visible:

@Kruno313 since you haven't mentioned which font are you using, I assume it's Inter. Inter is a default font used in our templates.

I uploaded Inter font into https://fontdrop.info/ font viewer webapp, and input your text x0x1234.

Avalonia renders this text as expected from the font. I am closing this issue as by design.

TextBlock should not change text. Searching and replacing makes it only slover for no benefit, making only problems.

@Kruno313 it's also possible to disable specific font features:

<TextBlock Text="x0x1234" FontFeatures="-calt" />

Thanks.
I have never heard about this and never noticed it in Win-Framework or other Libraries (I use the Hexadecimal formatting often).
