I noticed that you made this message empty with a control character:
Is there a reason for this?
Hi User:Amire80, I noticed this message (MediaWiki:Advancedsearch-field-preview-sort/bn) used with other three message (MediaWiki:Advancedsearch-sort-preview-create-timestamp-desc/bn, MediaWiki:Advancedsearch-sort-preview-last-edit-desc/bn, MediaWiki:Advancedsearch-sort-preview-relevance/bn) to form a sentence (e.g. "Sort by creation date").
Because of Bengali grammatical structure, i needed to do that. In Bengali "creation date" (তৈরির তারিখ) comes first, then "by" (অনুযায়ী), then "Sort" (বাছাই করুন). Same thing with other two messages. So, i made that message empty & move that part into other three message.
If i broke something, i can revert this. but then translation would be long & little bit odd. My suggestion is if possible make this message (MediaWiki:Advancedsearch-field-preview-sort/bn) as "Sort by $1", so i can easily translate & make adjustment.
