WebGL with Japanese and Chinese Font files won't run in Chrome

[tmiller_vb]

Hi there.

I am in the process of localizing my app into multiple languages, and was doing absolutely fine until I built and ran the WebGL build. I am using Unity 5.0.2 on Mac OSX.

My first attempt showed that Japanese and Chinese characters didn’t show up at all, in any browser. It works in Unity, on iOS and Executable builds, and in WebPlayer mode, but not WebGL. In this case, I was using a regular font that could also display Japanese and Chinese characters.

After that didn’t work, I added in a couple of fonts that would respectively focus on Japanese and Chinese, and then I rebuilt for WebGL. It worked in Firefox perfectly. However, Chrome now crashes when the loading bar fills up.

This crash occurs if I just happen to have the fonts in the Resources folder, even if I’m not referencing them anywhere in my app.

I am very confused. Has anyone tried to use WebGL along with localization into Chinese or Japanese? Any help would be appreciated.

The need to add fonts to your project is expected. From the docs (Unity - Manual: Font assets):

Note that some target platforms (WebGL, some consoles) do not have OS default fonts Unity can access for rendering text. For those platforms, Include Font Datawill be ignored, and font data will always be included. All fonts to be used as fallbacks must be included in the project, so if you need to render international text, you need to supply a font which has the required characters, and set up that font in the Font Names list of other fonts.

The crash in Chrome might be a memory issue, possibly caused by the bigger data file. If you provide a repro case (Ideally by reporting a bug and quoting the ticket number here), we can take a look.

Thanks! It did turn out to be a memory issue. I didn’t think a couple font files would add much, but it apparently did. I’ve reduced the file size and now it works as expected.
