Before you pick a styled name, know what PUBG Mobile’s system does when you submit one.
Length limit
PUBG Mobile caps player names at roughly 14 characters. Each Unicode character counts individually, even when it’s part of a multi-byte substitution. A ten-letter name in Bold Italic is still ten characters — but each of those characters is visually wider, so the name may appear truncated in crowded match UI like kill feeds and scoreboards.
What the system rejects
PUBG filters several categories of input during name validation: offensive content (checked against a regularly-updated word list), combining diacritics stacked into "zalgo" text, and certain invisible characters. None of the sixteen styles on this page use combining diacritics, so they pass the filter. Offensive content is about what you type, not how you style it.
What the system accepts
Mathematical Alphanumeric Symbols (Bold Sans, Bold Italic, Bold Script, etc.), Enclosed Alphanumerics (Circled, Squared, Bubble), typographic variants (Small Caps, Wide), and decorative wrapper symbols (Stars, Hearts). All sixteen styles in the tool above work in PUBG name fields — though the wrapper styles do add extra characters that eat into the 14-character limit.
