Lookup Common Abbreviations

There is a large list of common abbreviations set-up alread and it will use them by default. You can set this to false to not use them.

Keep Typical AllLowers

Typically, words such as:

"and", "as", "at", "for" etc, even in a title are always lowercase and this is the default behaviour. Set this to false to ignore this.

Format Measurements

Measurment abbreviations and symbols have a specific case. I.e. Gpbs, Hz, kWh. When converting the function will pay attension to these and convert to the correct case. Set this to false to ignore this.

Additiional Actions

When something contains letters and number, or a mixure of special characters, they will be converted to all upercase. E.g. 293GH-34-IP-1A
It will pay attention to pleural abbreviations. E.g. CSV's or CSVs
It will try to work out an abbreviation not in the list of common abbreviatioins, by also looking up a real UK dictionary (up to four letters or less). For example. The word 'svs' in not in the list of common abbreviatioins, but it's also not a real English word and it's 4 characters or less, so will be treated an an abbreviation and convert to uppercase.
