Purpose: Title case (capital case, headline style)[1], example
"The Quick Brown Fox Jumps over the Lazy Dog"
[1] A mixed-case style with all words capitalised, except for certain subsets

AutoHotkey forum thread: https://autohotkey.com/boards/viewtopic.php?f=6&t=58981
TitleCase(Text[,lang="en",ini="TitleCase.ini"])
Options:
Text
The string to convert to TitleCase.
lang
Language (or actually "SECTION") to use (reads from ini). Default "en" (for English). You can add your own sections (see below).
ini
Ini-file to use. Default is
TitleCase.ini. If there is no INI present inA_ScriptDirit will create a default one, with "en" only.
The text is transformed first to AutoHotkey Title case format using StringLower
So "GONE with the WIND" would become "Gone With The Wind"
After that several (find and replace) functions are called to process exceptions in the order as outlined below in the INI setup.
Ini setup - All keys are CSV lists apart from the find and replace pairs defined by _find _replace:
[lang]
LowerCaseList= words you would prefer to have lowercase: a,and,is,the,etc [1]
UpperCaseList= words you would prefer to have uppercase: AHK,IBM,UK
MixedCaseList= words you would prefer to have MixedCase: AutoHotkey,iPhone
ExceptionsList= [2]
AlwaysLowerCaseList= final check to ensure that any of the actions above haven't transformed specific words
OrdinalIndicator_Find= Regular Expression to FIND
OrdinalIndicator_Replace= Regular Expression to REPLACE (see ordinal below)
Hypen1_Find=
Hypen1_Replace=
Hypen2_Find=
Hypen2_Replace=
[1] Also does: RegExReplace(Text, "im)([’'`])s","$1s") ; to prevent grocer'S
[2] Also does: RegExReplace(Text, "im)[\.:;] \K([a-z])","$U{1}") ; first letter after .:; uppercase
Apart from the CSV lists you can also define find and replace pairs in the INI to handle special use cases such as Ordinal numbers.
You can define a pair by using the same keyword and append "_find" and "_replace", example:
Hypen1_Find =im)-\K(.)
Hypen1_Replace=$U{1}These pairs are regular expessions and are used as follows:
Text:=RegExReplace(Text,pair_find,pair_replace)
"Ordinal numbers may be written in English with numerals and letter suffixes: 1st, 2nd or 2d, 3rd or 3d, 4th, 11th, 21st, 101st, 477th, etc., with the suffix acting as an ordinal indicator."
-- https://en.wikipedia.org/wiki/Ordinal_numeral
English is included by default, a possible example for French is provided below.
OrdinalIndicator_Find=im)\b(\d+)(st|nd|rd|th)\b
OrdinalIndicator_Replace=$1$L{2}OrdinalIndicator_Find=im)\b(\d+)(er|re|e)\b
OrdinalIndicator_Replace=$1$L{2}The ini-file can have multiple [Sections] for specific languages or situations. Or you can prepare a different INI file for each situation.
Note: If you prepare your own ini files be sure to use UTF-16 encoded files to ensure proper processing of Unicode / extended ASCII characters. See the AutoHotkey IniRead documentation.
