unicode U+00E1

unicode

unicode 'latin small letter a with acute'

You can specify a range of characters as argumets, unicode will show these characters in nice tabular format, aligned to 256-byte boundaries. Use two dots ".." to indicate the range, e.g.

unicode 0450..0520

will display the whole cyrillic and hebrew blocks (characters from U+0400 to U+05FF)

unicode 0400..

will display just characters from U+0400 up to U+04FF

Tabular format does not deal well with full-width, combining, control and RTL characters.
