Struct UnicodeNeutralizationConfig

    pub zero_width_action: ZeroWidthAction,
    pub homograph_action: HomographAction,
}

Unicode neutralization configuration

Controls how unicode-based security threats are handled. These attacks exploit unicode features to deceive users or systems.

Fields

bidi_replacement: BiDiReplacement

How to handle BiDi characters

Default: Marker (visible indication) Security: BiDi characters can reverse text direction to deceive users.

• Remove: Most secure, may break legitimate RTL text
• Marker: Balance of security and usability (recommended)
• Escape: Preserves data but may confuse users

zero_width_action: ZeroWidthAction

Action for zero-width characters

Default: Remove (most secure) Security: Zero-width characters are invisible and used for:

• Hidden tracking codes
• Bypassing filters
• Creating invisible URLs Warning: Some languages legitimately use zero-width joiners

homograph_action: HomographAction

Action for homographs

Default: Ascii (convert lookalikes) Security: Homographs look like ASCII but aren’t (е vs e).

• Ascii: Converts to ASCII equivalent (most secure)
• Warn: Alerts but preserves (for international apps)
• Block: Rejects content entirely (strictest)
