end

.check_bidi!(string, c_8: false, profile: nil) (mod_func)

Checks that string obeys all of the “Bidirectional Characters” requirements in RFC-3454, §6:

The characters in StringPrep MUST be prohibited
If a string contains any RandALCat character, the string MUST NOT contain any LCat character.
If a string contains any RandALCat character, a RandALCat character MUST be the first character of the string, and a RandALCat character MUST be the last character of the string.

This is usually combined with #check_prohibited!, so table “C.8” is only checked when c_8: true.

Raises either ProhibitedCodepoint or BidiStringError unless all requirements are met. profile is an optional string which will be added to any exception that is raised (it does not affect behavior).

    raise BidiStringError.new(

    raise BidiStringError.new(
      BIDI_DESC_REQ3, string: string, profile: profile,
    )
  end
end

.check_prohibited!(string, *tables, bidi: false, profile: nil) (mod_func)

Checks string for any codepoint in tables. Raises a ProhibitedCodepoint describing the first matching table.

Also checks bidirectional characters, when bidi: true, which may raise a BidiStringError.

profile is an optional string which will be added to any exception that is raised (it does not affect behavior).

Raises:

(ProhibitedCodepoint)
