Description

https://commons.wikimedia.org/wiki/File:Latin_letter_K%C4%B8_(kra)_RSVG-BUG.svg is rendered wrongly:

512px-Latin_letter_Kĸ_(kra)_RSVG-BUG.svg.png (164×512 px, 3 KB)

How it should look like:

512px-Latin_letter_Kĸ_(kra).svg.png (164×512 px, 5 KB)

It seems there are some flags which do not need to be seperated, but librsvg does not understand 001 as 0 0 1, but it should.

A explantation what is going on:

Such SVG can be "repaired" (lossless workaround) using https://svgworkaroundbot.toolforge.org/ (enable "run svgcleaner").

The "fix" at https://commons.wikimedia.org/wiki/File:Olympic_rings_-_SuperTinyIcons.svg added 40 bytes - defeating the point of having a "SuperTinyIcons" version of the logo.

Also, after it was fixed, another editor tagged the SVG as "The source code of this SVG is invalid due to an error" and "This SVG text-logo may show a librsvg bug".

The actual fix is much smaller, but requires hand-editing the file instead of using the automated fix. I've done so.

Also, after it was fixed, another editor tagged the SVG as "The source code of this SVG is invalid due to an error" and "This SVG text-logo may show a librsvg bug".

The validation error is not display related, it's complaining about an aria-label attribute where one isn't supposed to be according to the standard.

Confirmed fixed, though I note that the first image in this list shows 4 K's, but the current version only shows 2K's not sure why. But the others all seem to be working.

Kashmiri added a comment.May 17 2023, 3:23 PM

It's because only two K's are there in the code. Not sure why the other two K's have been removed when creating this file.
