Most pages about fancy text state things confidently and cite nothing. That is a low bar, and clearing it is the main reason this site exists in the form it does.

Every factual claim here has to be one of four things.

1. Verified from a primary source

Platform rules come from the platform's own documentation wherever it exists. Instagram's username rules come from Instagram's Help Center. Discord's formatting syntax comes from Discord's support article. Where a platform documents something, that is what we use.

2. Corroborated across independent sources

Where no primary source exists, most character limits fall into this category, we require agreement across several credible independent sources before stating a figure.

3. Derived from the Unicode database

Every technical claim about characters is generated rather than written: codepoint ranges, which letters exist in a set, which are reserved, which styles cover digits. The style maps and symbol sets are produced by scripts that read the Unicode database and validate as they go, refusing to output anything unassigned, duplicated, or mapping to whitespace.

This is the most reliable category on the site, and it is checkable. Every style shows the codepoint of the block it comes from, and you can look it up.

4. Explicitly hedged

Where the truth genuinely varies, the page says so rather than picking the answer that reads better. TikTok's bio limit is reported as both 80 and 160 characters by sources we would otherwise trust, so the bio builder shows a live character count with no limit and labels the field as unverified. Whether a styled character counts as one or two against a platform's limit depends on how that platform counts, so we tell you to paste and check rather than asserting a number you might rely on.

What gets left out

Things we could not establish are absent rather than guessed. Instagram's comment character limit, currently reported as both 2,200 and 1,000. Facebook's exact name-change frequency. Engagement statistics of the kind competing pages present as fact, at least one of which is openly labelled "estimated" on the page it appears.

An absent figure is a decision, not an oversight.

Corrections

Errors get corrected and the page's last-updated date changes. If you find one, the contact page is the fastest route, and a report that a character renders as an empty box on a specific device is the single most useful message we receive, because there is no way to test every style on every phone.

Where this process is weakest

Platform rules change without announcement, and a one-person site checks them less often than a platform changes them. The technical Unicode claims are stable, because Unicode is stable. The platform claims are the ones most likely to drift, and they are dated so you can see how much to trust them.
