VS Code regex replace changes capitalization cases

readme.md

Capitalizes the first character, lowercases the rest

Regex used was a simple/flag Or list,

Regex: (count|SUBSET|Hold|Then|Else|end|subset|Concat|if|\beq\b|int|trim)
Replacement: \u\L$1

docs

• from the docs

This is done with the modifiers \u\U\l\L, where \u and \l will upper/lowercase a single character, and \U and \L will upper/lowercase the rest of the matching group.

The modifiers can also be stacked - for example, \u\u\u$1 will uppercase the first three characters of the group, or \l\U$1 will lowercase the first character, and uppercase the rest. The capture group is referenced by $n in the replacement string, where n is the order of the capture group

If you use short segments first, you can use sub-word capitalization

For example: Compare the final capitalization

regex  : (bat|man|batman)
pattern: batman
result : BatMan

regex  : (batman|bat|man)
pattern: batman
result : Batman
