Description

I have a menu with buttons, which can be strikethrough or usual
Before update to Telegram 6.1.2, it was looked as usual -> strikethrough worked correctly,
After update -> I understood that localization of these strikethrough numbers was changed and it isn't working appropriately.
As we know, buttons are not maintaining strikethrough text directly via "<s></s>", so I've used Unicode characters to make them as they should be:
Unicode Character 'COMBINING LONG STROKE OVERLAY' (U+0336)
0 -> "\u03360\u0336";
1 -> "\u03361\u0336";
2 -> "\u03362\u0336";
3 -> "\u03363\u0336";
4 -> "\u03364\u0336";
5 -> "\u03365\u0336";
...
etc.

But now it works inappropriately, bot outputs: <LONG_DASH>0<LONG_DASH>.

Expected Behavior

Strikethrough workes correctly,

Actual Behavior

Output of strikethrough changed to: <LONG_DASH>0<LONG_DASH>.

Screenshots and Videos

Environment

Device: iPhone/iPad X

iOS version: 13.X

App version: 6.1.2

No source file or test is identified. Start by reproducing the menu-button behavior on iOS 13.x with Telegram 6.1.2, using the listed Unicode combining characters, then trace the localization or text-rendering entry point. Done means strikethrough digits render correctly instead of as LONG_DASH characters.
