I guess maybe the charset of the XHR is wrongly set for this RE inline search field.

Is it new problem ? I frequently use this inline label search with this kind of names without problem So either it's a problem with just this label and other few either it's a new problem.

edit Actually, the problem comes from « ・ » U+30FB KATAKANA MIDDLE DOT character as if I searh either only マーキュリー or ミュージックエンタテインメント I find the label.
But usually I don't remember having problems with this chracter in previous RE label searches.
