There is no function that just 'knows' that 'notemachine' is two words
and should become 'NoteMachine'.
Any chance that 'notemachine' is stored with a zero-width space (Unicode U+200B)? This is common for compound words where the programmer wants to be able to "know" that they are distinct words that are smashed together.
select initcap('notemachine'), initcap('note' || U&'\200B' || 'machine');
initcap |initcap |
-----------+------------+
Notemachine|NoteMachine|
You could check the length() of the string. If it is 12, there is an invisible character in there. This would explain the "unexpected" behavior that no one seems to be able to replicate.
