Description
I tried creating some text on a bitmap using korim: "test Ą/Ę"
but the resulting bitmap end up looking like this ↓

Characters on the following screenshot are aligned to the bottom instead of the center, and that makes characters like: Ą or Ę look odd.
i used the following snipped to render the text on the bitmap:
```kotlin
generatedFrame.drawText(
str = "test Ą/Ę",
font = resourcesVfs["font.ttf"].readTtfFont().toLazyBitmapFont(300F),
size = 90F,
pos = Vector2(
x = (generatedFrame.width / 2.0) - (textMetricsData.metrics.width / 2.0),
y = (generatedFrame.height / 2.0) - (textMetricsData.metrics.height / 2.0)
),
alignment = TextAlignment.TOP_JUSTIFIED
)
```
also, the font I used is [Bebas Neue](https://fonts.google.com/specimen/Bebas+Neue?query=bebas)

Research direction
Start by reproducing the Kotlin snippet with Bitmap.drawText(), the string "test Ą/Ę", and the Bebas Neue font. Inspect the text metrics and TOP_JUSTIFIED alignment path used during bitmap rendering. Done means characters with tails, including Ą and Ę, are positioned consistently with the requested centered placement.
