Today I got an upvote for my answer to

Looking at the question it is apparent that looking up for a symbol is unsuccessful. One finds similar symbols only with
mathdesign. Using the latter package forces a global change of fonts, using the former changes all the math symbols and exposes to the infamous “Too many math alphabets” error. More than that, only two out of three symbols are available, even if one chooses one of these ways for solving the problem.
Closing as duplicate of How to look up a symbol or identify a math symbol or character? should be reserved to cases where the method is effective, not when the symbol doesn't exist or exists only “partially” (requiring `MnSymbol' or other packages that cannot generally be used in a document). In some cases, the question might more sensibly be a duplicate of Importing a Single Symbol From a Different Font; the question I'm referring to isn't.
It happened again. The requested symbol is available only with
MnSymbol and this is NOT (yes, I'm shouting) a solution.
We CANNOT close a question as duplicate of “How to look up a symbol” if the symbol is NOT available.
