Improve or customize title case algorithm?

For example, I have a book titled "THE EFFECT OF pH, TEMPERATURE AND TIME ON CHEMICAL STABILITY"

I select "Change case > Title case" in the metadata editor.

The title is now "THE EFFECT OF pH, TEMPERATURE AND TIME ON CHEMICAL STABILITY".

I guess the lowercase p in pH is confusing Calibre?

A bit weird. When I apply titlecase, your original title changes the 'THE' to 'The' leaving the rest of the title alone. If I convert to upper case, lower case or change pH to PH, then title case seems to work though you will have to manually correct Ph to pH after applying title case. Not sure if this edge case is worth worrying about.

It's a pretty common situation for me, any time the title is mostly all caps with a few lowercase letters or words.

A regexp would probably do it for you; e.g., search/match <h2>(.)(.*)</h2> and replace with <h2>\1\L\2</h2>; that's how I do it in Sigil in one fell swoop. Then I go back and find the proper names and whatnot and upcase their first letter with Alt+U.

Is there a way to apply a regexp to a book title in Calibre though? That's what I'm looking for.

many CASE tools I have used, expect to start with Lowercase., so my routinne is:
Lower
Title
(touch up the odd usage)
