Karla Tamil Inclined & Upright – Missing Characters in Menu Variant

**Describe the bug**

The "menu" font variant for [Karla Tamil Inclined](https://fonts.google.com/specimen/Karla+Tamil+Inclined/glyphs?query=karla) & [Karla Tamil Upright](https://fonts.google.com/specimen/Karla+Tamil+Upright/glyphs?query=karla) fonts are missing the necessary characters to render the font family name correctly in font pickers.

```
// Inclined
"menu": "https://fonts.gstatic.com/s/karlatamilinclined/v2/vm8pdQ3vXFXZ1aPd8dNzR82AFh2TibkaVocat5I.woff2"

// Upright
"menu": "https://fonts.gstatic.com/s/karlatamilupright/v2/IFS4HfVMk95HnY0u6SeQ_cHoozW_3U5XkBN3hQ.woff2"
```

**To Reproduce**
Currently, Karla Tamil Inclined and Karla Tamil Upright shows in the fallback font.


**Expected behavior**

The "menu" font variant should include all characters needed to render the full font family name. These characters can be reused from its latin-only variant - [Karla](https://fonts.google.com/specimen/Karla?query=karla).

**Additional**
It would be beneficial to treat the inclusion of these menu characters as mandatory for all font families.
