About
Standard digital typography restricts users to a single font family and weight, severely limiting creative expression on platforms like Instagram, Twitter (X), TikTok, and LinkedIn. The Bold Text Generator acts as a transcoding engine, mapping standard Latin ASCII characters (x) to Mathematical Alphanumeric Symbols and other Unicode blocks (๐ฑ, x, x). This allows for rich text simulation in environments that officially support only plain text.
Unlike basic lookup tools, this application features a Semantic Protection Layer. Algorithms analyze the input stream to identify functional tokens - specifically hashtags (#tag) and mentions (@user). By default, these tokens are excluded from transformation. This is critical because social media indexing algorithms perform exact string matching; converting a hashtag to Unicode bold renders it invisible to search, killing the post's discoverability. We solve this by applying styles selectively, ensuring your aesthetics never compromise your analytics.
Formulas
The core transformation utilizes a modular arithmetic approach for contiguous Unicode blocks. For a given input character code c, the output glyph code point P for a style starting at offset O is calculated as:
However, many aesthetic styles (like "Small Caps" or "Upside Down") do not exist in contiguous blocks. These rely on Dictionary Mapping Map(c):
