Update Polish translation

[alemart]

Hi @suve . Did you receive my e-mail? We're releasing a new version of the game in the next few days. How is the translation work going?

[alemart]

@suve Please submit your translation no later than August 30th, so that I can ship it for the players with the new version of the game - to be released this week. Thank you.

I have opened PR #75 to address this.

I looked a bit through the game's menus before submitting and noticed one instance where the font is missing a Polish letter - this being in the main menu. The "exit" text is missing the "Ź" letter.

The most straight-forward solution is to extend the font and add the missing character, but as far as I can see, in-engine, bitmap fonts only support ASCII. I have tried to circumvent this by using one of the non-printable ASCII characters (namely, ESC) but that made the game crash with the following error:

nanoparser error! Lexical error in "languages/polish.lng" on line 133: unknown symbol  (27).

If you could give me some tips on how to work around this, it'd be great. Alternatively, if this is too big of an issue to late into the release schedule - you could work around by simply changing the translated text from WYJDŹ to WYJDZ (i.e. change the Ź to your usual latin Z). It won't be perfect, but people should have no problem understanding it.

Hi @suve,

You can just use a TrueType font instead. We're currently taking this approach for the Russian, Bosnian and Serbian translations. Add the following entry to file fonts/title_screen.fnt:

font "Title Screen - Menu Item" for "pl_PL"
{
    truetype
    {
        source_file             "fonts/Roboto-Black.ttf"
        size                    12
        shadow
        antialias
    }
}

Let me know if it works for you.

It's too late to change the bitmap fonts or the engine now, but using a TrueType font should work fine.

I await your modifications today. Thank you.

[suve]

Huh. For some reason, I was fiddling with fonts/boxy_bold.fnt instead of title_screen.fnt. I guess because I didn't see a title_screen.png.

Anyway, after experimenting a bit, it turns out that while some ASCII chars cause the error mentioned above, some don't - e.g. DEL works fine.

So, I can update the PR either way:

1. Encode the Ź using DEL and update the bitmap font.
2. Use a TrueType font for the Polish title screen text.

I have both patches ready, so just let me know which one you prefer.

[alemart]

Use a TrueType font.

Even though using DEL would work, this isn't the ideal approach because we also support other languages. Letter "Ź" belongs to unicode block Latin Extended-A, which is (currently) not supported when using bitmap fonts.

[suve]

I've updated the PR to use a TrueType font. I tried a couple of different weights and sizes to pick one that looked best to me.

[alemart]

Thank you very much.
