Dialect differences

Both TSV and HTML are file formats, so what differs below is how each one chooses to represent a value.

Property	in TSV	in HTML
identifiers	`Rarely used, which is exactly why tabs in data break it`	`Attribute values in quotes; entities for reserved characters`
dates	`Conventional text: 2026-09-18 or 2026-09-18 14:30:00`	`Whatever text was rendered`
binary	`Not supported - must be encoded`	`data: URIs inside src attributes`
separator	`Tab`	`Tags, not delimiters`
encoding	`No declaration - UTF-8 works only with a BOM`	`Declared in a meta charset tag or the HTTP header`
typing	`None - every field is text`	`None`
shape	`Flat table, optional header row`	`Free form; tables are row/column structures inside markup`
