Ability to disable Emojis in Job Names

#23349 introduced support for emojis and other non-UTF-8 characters in job names, etc.  While I appreciate the excitement for this support it can cause problems in a corporate environment and [opens the door for potentially misleading and/or malicious URIs|https://krebsonsecurity.com/2018/03/look-alike-domains-and-visual-confusion/].

My ask is for a global setting that can be triggered to disable this support.
