I’m writing a small quiz game for the browser. The problem I’m getting is that the Japanese characters aren’t rendering in browser (HTML5 build).
Editor:
Browser:
I’m using Japanese characters in my code like so
private Dictionary<string, string> quiz_answers = new Dictionary<string, string>(){
{"a", "ア"}, {"i", "イ"}, {"u", "ウ"}, {"e", "エ"}, {"o", "オ"}
};
I’ve tried converting them to unicode characters but I think it doesn’t change anything.
'\u30A2'.ToString()
I had the same problem.
It turned out that the font I was using didn’t support the special characters I was using. It worked nontheless in the editor and in PC-builds, because in these cases Unity uses a different fallback-font to render the special characters. But in WebGL-builds, Unity can’t access these fallbacks:
From Unity - Manual: Font assets
Note that some target platforms
(WebGL, some consoles) do not have OS
default fonts Unity can access for
rendering text. […] All
fonts to be used as fallbacks must be
included in the project, so if you
need to render international text or
bold/italic versions of a font, you
need to add a font file which has the
required characters to the project […]
To find a font that supported the special characters I needed, I used the Windows character map (Press Windows-key + R, then type “charmap”) as well as pages like Unicode Character 'LEFT RIGHT DOUBLE ARROW' (U+21D4)
I found a font that had everything I needed, and I am using that font as my main font. You can use the font as a fallback-font instead, just read the first page I linked to.
The Unity manual also says:
Note that fonts are subject to copyright and you should only include fonts that you have licensed or created for yourself.
It can be hard finding a completely free font that support some special characters. If so, you have to pay for a license (even fonts like Arial requires a license when embedded in applications)
