Bug: First letter in Title Case not Uppercase when preceded with numbers or special characters

[ekarious]

• [x] I have verified that I am on the latest version of the Linter Linter version 1.25.0

Describe the Bug

When having a title like this

135_  A letter arrived

It gets formatted as

135 - a Letter Arrived

If the letter is in the lowercase words, It will be lowercased even if first letter in the header.

How to Reproduce

Steps to reproduce the behavior:

1. Make a title similar to mine as the first word is not a letter
2. Set Capitalize Headings to Title Case
3. Ignore Cased Words to false
4. Lowercase Words should have a inside for this example.
5. Format the file
6. See error in the first heading

Expected Behavior

As the linter run, the header

135_  A letter arrived

should have been

135 - A letter arrived

Device

• [x] Desktop
• [ ] Mobile

Additional Context

As additional context, take note that I am currently using a regex to modify the header to change _ -> - as: ^# (\d+)_ (.+)\n gm # $1 - $2\n As I am not an expert in regexes, maybe this can contribute to the bug.

I know another issue was filed and fixed for this in 2022. But I still have the bug in my vault.

Hey @ekarious , thanks for reporting this. This seems like the regex for finding valid words is likely hitting an issue where it is matching all digits. I do need to verify this though.

Ok. I took a look and it looks like the issue is because it is not properly filtering out some single letter situations. It looks like if - or ' are by themselves with whitespace around them in the header before any letter, it gets considered to be the first "letter". This should not be too hard to fix (fingers crossed).

Thanks for bring this to our attention.

I believe I have a fixed that is now merged into master and should go out with the next release. Please let us know if there is an issue with either.
