Right to left text drawn in opposite order.

[dhtdht020]

Describe the bug
Right to left languages, like Hebrew, display incorrectly through Ruffle.

Rather than drawing the letters from right to left, they are drawn in the opposite order.
So the following text (in hebrew): Hello
Appears as: olleH
Note that this is not a problem with the font difference, rather the ordering of the letters.

Expected behavior
The text should be drawn from right to left.
In this specific example, the white text below the orange clock should be drawn as it does in Adobe Flash Player, to support flash animations that include RTL languages:

Is the problem with the Ruffle desktop app, extension, or self-hosted version?
I have tested this problem in both the Ruffle desktop app, and the (chrome) extension.

What platform are you using?

Weird, using nightly from 2021-12-10 at https://ruffle.rs/demo/, I get only x.

I wonder whether this may be a regression.

@ousia took a look as well by comparing the version I've originally used and nightly 2021-12-10, I can confirm it appears that hebrew doesn't properly display anymore.

@dhtdht020, how about opening a new issue with the regression displaying embedded font?

Thanks, done that, #5839

@dhtdht020, the issue about displaying Hebrew characters has been fixed.

Could you confirm that Hebrew text isn’t displayed right to left (as it should be)?

Many thanks for your help.

@ousia Can confirm Hebrew text is not displayed right to left.

[ousia]

@dhtdht020, is it just me or are Hebrew characters not being displayed again?

Can confirm that it seems things have regressed again.

[ousia]

@dhtdht020, just reported the issue.

Many thanks for your confirmation.

@dhtdht020, after @n0samu stated that this SWF doesn’t really use the glyphs from the embedded font, I wonder whether the lack of R2L is due to a flaw in Ruffle or the provided SWF isn’t properly tagged.

Could you check whether the Hebrew version (or other RTL text) is working properly in https://htwins.net/scale2_old/?

Many thanks for your help.

[n0samu]

Right-to-left text is not rendered correctly in Ruffle at the moment, this is a known issue. If you see proper right-to-left text in any content, that would be because it is in the SWF as a bitmap/image rather than a text field.

@ousia I can confirm that the Hebrew version of the Flash app in the provided URL renders correctly and in the right order, with Nightly 2024-02-03.
