- ASCII Special Characters: Symbols and spaces are replaced with a single underscore (“_”) since they are represented in 1 byte.
- Accented and Extended Unicode Characters: Characters with accents (e.g., “ó”) are replaced by a double underscore (“__”), reflecting their 2-byte representation. The 3-byte and 4-byte Unicode characters are replaced with three (“___”) and four (“____”) underscores, respectively.
