Ruffle Info

Version: 0.1.0 Name: nightly 2021-01-29 Channel: nightly Built: 2021-01-29T00:34:32.424Z Commit: bb4240ad1f9705b080c9f7861e38b6677a62d76b

I noticed that it seems to be occasionally displaying some garbage text. My assumption is that the text is encoded in Shift-JIS, but is attempted to be rendered as if it were in Unicode. That may have something to do with the crashing I've been experiencing.

For example, if you open the panel numbered 95, then scroll through you'll see garbage text such as "AfjXVNJthVbvJbvccB" and "fjXZfGXgBw@BliAeB[NEMAEJIXEWCAgjxZAq|ijccB". If you keep scrolling, eventually Ruffle crashes (and gives the option to submit the above error report).

Hi @SnorlaxMonster, it looks like you are using a very old version of Ruffle. Do you have an outdated extension installed? If so, you should install the latest version from the Chrome Web Store instead: https://chrome.google.com/webstore/detail/ruffle/donbcfbmhbcapadipfkeojnmajbakjdc

This crash does not occur in the latest version of Ruffle. But the garbage text remains, so I agree that Ruffle must be misinterpreting the text encoding. Thanks for the report!

[SnorlaxMonster]

@n0samu Ah, it seems like I had to actually uninstall Ruffle and reinstall the latest version from the Chrome Web Store to actually get it to update. Updating Ruffle seems to have resolved the crashing issue, and some other corruption of images that I was also getting.

However, as you noted, the character encoding issue still appears to be present. Should I open a separate issue for the character encoding problems?

[n0samu]

I don't think you need to open a separate issue. Looking into this more, I found that the text is loaded via CSV spreadsheet files that use SHIFT-JIS encoding, for example: https://www.tv-tokyo.co.jp/anime/yugioh-arcv/duel_juku2/data/cnd095.csv And loading this game with real Flash Player (on an English Windows system) results in garbled text, too. So I guess Flash Player's behavior depends on the system locale. Ideally Ruffle should use a text encoding detection library to deal with cases like this automatically in a locale-independent way, I think.

Similar to #8390

[SnorlaxMonster]

The original issue I had was resolved. The remaining issue is a duplicate of #8390

[n0samu]

No, this is not a duplicate issue. This SWF is not version 5, it is version 9. This problem is with loading external text with non-UTF8 encodings, not with SWFv5 internal text fields.
