It looks like rowiki defined a custom message including the <b> tags at: https://ro.wikipedia.org/w/index.php?title=MediaWiki:Search-interwiki-default&action=edit

In the code we only escape the message, we don't parse it with the wikitext parser. We can change it to parse as wikitext if necessary.

For reference, the message provided by the code for en:

In the translation files for ro.json:

Perhaps T146655 will remove the perceived need to wrap the title in <b> ? It puts the footer in a heading tag, making it more prominent. Not directly related, but ro.wikipedia.org may want to consider configuring https://ro.wikipedia.org/wiki/MediaWiki:Search-interwiki-custom to give each project a specific name instead of falling back to the search-interwiki-default message that uses the hostname. This is done on other wikis, such as https://en.wikipedia.org/wiki/MediaWiki:Search-interwiki-custom

looks like the custom message has been removed on rowiki

i was completely looking at the wrong page ... it's not fixed yet. I still think the right solution is to remove the tags from the message

We need someone with admin rights on this wiki in order to fix this. Moving this to the backlog until someone from rowiki can help — @AdiJapan and / or @XXN ?

@CKoerner_WMF can you help with this?

maybe @Giku can help here?
