Research direction

Start by reading the AvoidSmartQuotedString prototype in PSRules and the existing UseBOMForUnicodeEncodedFile rule documentation in PSScriptAnalyzer. Determine how a new analyzer rule is structured and tested, then define completion as detecting unintended smart-quoted strings without producing a misleading BOM warning.

Description

Issue - Discussion

Background (excerpt from Wikipedea Quotation mark definition):

Regarding their appearance, there are two types of quotation marks:

  • '…' and "…" are known as neutral, vertical, straight, typewriter, dumb, or ASCII quotation marks. The left and right marks are identical. These are found on typical English typewriters and computer keyboards, although they are sometimes automatically converted to the other type by software.
  • ‘…’ and “…” are known as typographic, curly, curved, book, or smart quotation marks...

Summary of the new feature

Quoted strings are sometimes unintendedly replaced when passed by word processors as Microsoft Office applications as MSWord and Outlook. It is recommended to surround strings with unambiguous single quoted or double quoted string as it unnecessary triggers the UseBOMForUnicodeEncodedFile rule with no clear indication of the location.

Proposed technical implementation details (optional)
