Text Validation

Purpose

This capability determines if content represents meaningful text, preventing the processing of binary data as text which could lead to errors or corruption.

Requirements

Requirement: Heuristic Validation

The system SHALL validate decoded text content using heuristics such as the ratio of printable characters and control characters.

Priority: High

Scenario: Validate text

• WHEN decoded text is analyzed

• THEN it is classified as valid text only if it meets configured heuristics (e.g., sufficient printable characters)

Requirement: Profile Support

The system SHALL support configurable profiles for textual validation to handle different definitions of “valid text” (e.g., terminal safe, printer safe).

Priority: High

Scenario: Use profile

• WHEN validating text with a specific profile

• THEN the validation logic respects the profile’s allowed and rejected character sets
