character is looking for a loving home

[Martin]

Recently the character µ  (Unicode U+00B5) has started showing up in our texts.

So I manually added it via > Valid Characters > Manual Entry into our vernacular writing system.

Now in our Flex database it has settled in the Word-Forming-List and refuses to be shifted to the Punctuation-and-Symbols-List.

This new character is puzzling. A lot is written online.

It is listed as:

Category:  Ll / Letter, lowercase (although I am talking about our use of the position 00B5, not 03BC)

Sub-Block: Latin-1 punctuation and symbols


For this detail, I do not want to criticis Fieldworks, we just want to get things right. It "feels wrong" to have this character listed as a word-forming-character. We do not need lexicon pages or sections headed by µ when we export or print a dictionary, for example.

Is there any need for action in our database?

Where will it show up in the sorting-order, if I leave it behave in default manner?

In CLDR a character like µ is not listed as a "character in use" and not even listed as "auxiliary character" even though it is plenty in use. So having it now listed as a word-forming in Fieldworks is giving me goosebumps. Please advise how to bestpractise this one.

Thank you.



TL/DR

The contexts where this character is coming up is education, science as in measuring things and registration with CLDR, where the main elements of the International System of Units are requested for entry.

So far we have in our texts these "words":
µg
µm
µs
µL [sic for the capital]
