and more recently in:

• 2020: "Add title="" to h* based on existing TOC -- suggestion for new feature (or plugin?)"

There were a few other discussions in there:

• Regex method
• Calibre's "Function mode"

But honestly, proper Title Casing is a very hard problem, and all tools I've tested have flaws. "Edge cases" wrong like:

• Names
• Acronyms
• Accents
• Roman Numerals
• Letters after punctuation

(For example, I do not recommend CapitalizeMyTitle anymore. Whatever algorithm they used years ago has progressively gotten worse, I believe ever since they got purchased by that rotten Grammarly.)

There are a few python libraries, like:

• titlecase

but this, too, has serious flaws.

Calibre does a decent job with ALL CAPS -> Titlecase... definitely one of the better ones.

What you would need is a custom TitleCasing plugin where you can check options (like what to do after hyphens).

Side Note: Personally, what I do when having to work on hundreds/thousands of chapter titles, is:

• Export a giant list of all titles.
  
  • For example, ripping out every <h2>ALL CAPS TITLE</h2>
• Run entire list through a capitalize tool.
• Run original list through secondary capitalize tool.
• Compare both lists together.
• Skim down list to make manual corrections.
  
  • Words like "of", "and", ...

Then I could easily map:

<h2>ALL CAPS TITLE</h2>

to the equivalent line in:

<h2>All Caps Title</h2>

and do a mass Search/Replace.

This means I could also have an "All Caps" title in the TOC while still keeping the "ALL CAPS" visually in the book itself (just like I described in Post #15).

Heh. Yeah, I still do a lot of manual stuff.

To this date, I still haven't found a satisfactory tool for me.

One of the best capitalizers I've found is in TeXStudio. It has an Edit > Text Operations > To Titlecase (smart) which is quite good.

So sometimes, I even copy/paste text into there, then run it, then paste back where needed.
