It seems the user input "→", the system wrapped it with

<span aria-hidden="true"></span>

, then it was included into

<meta name="description">

and

<meta name="og:description">

contents without being escaped.

<meta name="og:description" content="ハンガーメニューの編集方法が分からず困っています。関連ありそうな部分としては外観<span aria-hidden="true">→</span>ウィジェットに&hellip;" />

This is caused by ​https://github.com/WordPress/wporg-mu-plugins/pull/454

However, the existing tags being output are duplicating Jetpack opengraph tags.

For example, with an English support thread:

$ curl -s 'https://wordpress.org/support/topic/ssl-question-for-wordpress-domain-w-3rd-party-hosting/' | grep 'description"'
<meta property="og:description" content="Support &raquo; Installing WordPress &raquo; SSL Question for WordPress Domain w/ 3rd Party Hosting SSL Question for WordPress Domain w/ 3rd Party Hosting pfischer1 (@pfischer1) 7 hours, 58 minutes…" />

<meta name="og:description" content="I am planning to transfer a domain to WordPress.com. I still have a hosting plan elsewhere. That hosting provider charges for SSL cert. Does&hellip;" />
<meta name="description" content="I am planning to transfer a domain to WordPress.com. I still have a hosting plan elsewhere. That hosting provider charges for SSL cert. Does&hellip;" />

WordPressdotorg\Forums\Hooks::meta_description() likely should be replaced a filter on the Jetpack opengraph data.

The header unicode arrow code should also be updated to not affect unexpected locations (ie. attributes).

Filed ​https://github.com/WordPress/wporg-mu-plugins/issues/574 for the over-greedy replacements.

This can remain open to fix the duplicate opengraph tags.
