Developer documentation, technical blogs, and academic portals frequently include content that must never be translated: LaTeX math formulas ($$E=mc^2$$), inline code tags (<code>const x = 1;</code>), and template variables ({{user_id}}).
Automated token masking pipeline
The TranslateBeam TDN Tokenizer scans HTML text for code boundaries before passing content to translation engines:
// Tokenization Example
Source Text: "Call the `getUserProfile()` method with your {{api_key}}."
Tokenized: "Call the ___TDN_CODE_1___ method with your ___TDN_VAR_2___."
Detokenized: "Llame al método `getUserProfile()` con su {{api_key}}."
This deterministic token masking ensures code syntax, template tags, and math formulas remain intact across every translated language.
