French translations with shortcode using parameter values wrapped with double-quotes not parsing correctly

[cais]

I'm not exactly sure how best to describe this but see below for additional details including how I was able to reproduce.

As it is, I have test a few different plugins by a few different authors and found when a WordPress installation is set to use the "Francais" (forgive the lack of accents) most if not all shortcodes will have their parameters wrapped in "double-quotes" change to at least the first being a "double-right-arrow".

To the best of my understanding the "double-right-arrow" is correct as far as the translation itself is concerned (and should be followed by a closing "double-left-arrow", which is not necessarily the case I am seeing in my "visual" testing).

Also to note, the plugin itself does not need to necessarily have a French language translation available.

To reproduce, use any shortcode implementing parameter values wrapped in double-quotes and switch the site's default language to French. At a minimum the first "double-quote" will be changed to a "double-right-arrow" and the shortcode will not parse correctly. Also to note, the underlying "code" as viewed in the Text tab of TinyMCE (or even as automatically produced by the_excerpt) will display the original version of the shortcode as written.

PS: This may be "known" to a certain extent per @nacin.

Quick update ... further testing (as this is coming up for all the "French" sites I have been troubleshooting) has shown a short-term work-around. To temporarily "fix" this issue wrap the shortcode in <pre> tags.

This will apply the styles associated with the <pre> tag so some additional CSS may be needed on most sites employing this temporary work-around.

Can you supply a self-contained code example that duplicates the problem?

I have a feeling that this is being caused by an unregistered shortcode (one that is not added with add_shortcode(), as the quote conversion doesn't affect registered shortcodes.
See ​http://codex.wordpress.org/Shortcode_API#Unregistered_Names for more information.

(Just to add: This works for me in testing, with a registered shortcode, but fails as described with an unregistered shortcode)

Hmm ... it seems further testing proves out what you are describing. I am not able to reproduce it in all cases of shortcodes with double-quotes wrapping their parameters and suspect this is an issue much along the lines you are suggesting via that link. I would suspect this ticket can be closed (resolving as #wontfix).

My previous tests were misleading. I'll let the other plugin author know about the issue. Thanks!
