Hi,

I've been trying to draw a string containing unicode characters, but I'm not having any success.

Naively I've just been pasting the characters into the code like so:

g2.drawString("♠");

But the character simply doesn't draw.

I found a tweet from Rob from a little while ago saying there were some Haxe-related complications with drawing unicode characters; but it did also suggest there was perhaps a way.

Does anyone have any tips?

Thanks!

You'll have to set g2.fontGlyphs to something which contains the code points you want to draw (Kha uses bitmap fonts and creating bitmaps containing all unicode characters is sadly not feasible).

That's great Rob, thanks! Setting the fontGlyphs is fine for me as there's only a handful of characters I need to use anyway.

Incidentally, I did encounter some slightly strange behaviour whereby my unicode character wouldn't display at a couple of font sizes (strangely enough, at the sizes 12 & 24 where the rest of the text looked the best, so presumably it was at multiples of its "native" size). However, just as I was trying to isolate whether it was an issue with my code, or perhaps with the font itself, all of a sudden it started working fine - and it continues to work fine now.

So that remains a bit of a mystery...

An update to the "mystery" of the non-working sizes from my previous post:

It turns out the unicode characters weren't drawing for sizes 12 & 24 because those were the "fontSize" and "fontSmallSize" parameter values I was passing into the constructor for the instantiation of my Zui object.

If I change the sizes passed into Zui then those sizes stop working instead; and if I comment out the Zui instantiation entirely (as I had when writing my previous post) then all sizes work fine.

(Note: in all these cases I'm not actually using Zui for anything - I'm just instantiating it.)

So it sounds like this may actually be a Zui library issue instead...

Hey, feel free to open issue at Zui repo and we can investigate further. The font size parameters passed should only set g.fontSize internally.

@lubos Hey, thanks Lubos. I've just created an issue here: https://github.com/luboslenco/zui/issues/27

Just a quick recap since the recent server issues lost some posts:

• Since 17.9.1, the unicode glyphs have stopped rendering for me when running via Kode Studio on Mac OS X 10.9.5 (Intel HD Graphics 3000).

• I've uploaded a sample to KodeGarden (link below), but that also has an unusual (possibly unrelated problem) where it works for me (including the unicode glyphs) when I first click and follow that link, but if I then click "Compile & Restart" nothing renders whatsoever.
