I can’t give one of my pages its correct title. I have to use “0. arts & ego”. When I attempt to specify “arts & egoo”, your system rejects it, stating it should be “Arts & ego”. The ‘correction’ is incorrect.
Arts with a capital A is a proper noun, and my art isn’t proper (nor is it improper). It does not conform to proper, as in property (even though I enjoy proper tea). Arts with a capital A doesn’t acknowledge the arts with a capital ej thrib (or ee cummings, for that matter).
I’d understand why you might wish to enforce title case in the case of page titles, but in that case you’d enforce “Arts and Ego” (which is also wrong).
Can I suggest you come to terms with the existence of difference?
