GlyphIndexMathematical bold
Latin letters map to mathematical bold characters. The ordinary space remains unchanged.

Text Style Converter
Try a decorative Unicode style, then check which characters changed. Keep the ordinary spelling for places that need it.
Your text is processed on your device. This tool has no third-party scripts, and GlyphIndex never reads your clipboard automatically.
13 / 10,000 UTF-16 units Some characters count as two units.
JSON includes your input and the result. Keep the file private if the text is private.
CSV contains all inspection records. If the output exceeds 10,000 UTF-16 units, those records describe the input. Formula-leading cells start with an apostrophe; JSON keeps the exact text.

Try an example
Italic letters with a digit
The h maps to U+210E. The digit 2 remains unchanged and is reported as unsupported for this mapping.
Input text h2 Result ℎ2
Double-struck letter forms
These capitals use their existing letterlike-symbol code points rather than unassigned positions in a simple range.
Input text CHNZ Result ℂℍℕℤ
Characters without a mapping
The three supported ASCII letters change. The accented é and check mark remain exact and are reported.
Input text Café ✓ Result 𝐂𝐚𝐟é ✓
Fullwidth punctuation
Fullwidth mode maps printable ASCII U+0021–U+007E. Whitespace is left as entered.
Input text A1! Result Ａ１！
Mathematical monospace
This substitutes Unicode mathematical monospace characters; it does not install or select a font.

What each mapping covers
| Mapping | Supported input |
|---|---|
| Mathematical bold | ASCII A–Z, a–z, and 0–9. |
| Mathematical italic | ASCII A–Z and a–z, including the special italic h mapping. |
| Mathematical monospace | ASCII A–Z, a–z, and 0–9. |
| Double-struck | ASCII A–Z, a–z, and 0–9, including letterlike-symbol exceptions. |
| Fullwidth | Printable ASCII from ! through ~. Ordinary whitespace remains unchanged. |
Choose a style, then Convert. Read the result and the unmapped-character message together. Accented letters, other scripts, emoji, and some punctuation may stay unchanged, so a result can contain mixed styles.
These are different characters
The result uses different Unicode characters, not a font or a rich-text bold setting. Search, pronunciation, platform rules, and fallback fonts may handle those characters differently from the original letters.
Check before sharing
Paste into a draft first and check the result at its normal reading size. Use Unicode Inspector to compare characters if the destination changes them. Preview any later normalization as a separate step.
The input limit is 10,000 UTF-16 units. Unpaired surrogates are rejected. The supported character mappings run on your device, without a conversion service or account.
