How to convert text to bold or italic unicode
Some input boxes, like an Instagram bio or a profile name, give you no formatting buttons at all. This tool converts letters and digits into the bold and italic character shapes that exist separately in Unicode, so the emphasis survives anywhere you paste it. Nothing about the font is being changed: the characters themselves are different characters.
Only Latin letters and digits change. Unicode has no bold or italic variants for Korean, Japanese, Chinese or most other scripts, so those characters are passed through untouched and the count is shown with the result. The italic styles have no digit shapes at all, so digits stay plain there, and punctuation and emoji always keep their original form. Nothing is invented to fill a gap.
There is a real cost to using them. These characters were designed for mathematical notation, so screen readers often skip them or read them strangely, search and hashtag matching ignores them, and older apps or devices may show empty boxes. Use them for a short headline or a name, and keep ordinary letters for body text and anything that has to be read reliably.
Frequently asked questions
Unicode simply has no bold or italic variants for those scripts. Rather than invent something, the tool passes those characters through unchanged and reports how many were left alone.
Often not. Because they are mathematical characters, screen readers may skip them or announce them oddly, which makes them a poor accessibility choice. Keep them for short emphasis and use normal letters in body text.
