Press and hold one of the character softkeys to see how to produce that character using a sequence of keyboard
keys. Esc and Shift+Esc may be used instead of the semicolon to cycle forward or backwards through the possible
interpretations of a given sequence.
A given character may be represented by a single dedicated Unicode code point such as Á (0xC1), or a
combination of code points such as Á (0x41+0x301). Some characters have only one of these representations, others
have both. Enable "only single-code characters" (if available) to hide characters which do not have a single dedicated
code point, and block their keyboard key sequences.
Enable "lock focus" to make the focus automatically jump back into the text entry box after each softkey click.
When converting "to text from comma separated numbers", the numbers may be separated by any non-digit character(s),
and hex numbers may be preceded by 0x or 0X. For a sequence of 2-digit hex numbers without separation, use
this other tool
to insert separators, then paste the result here and complete the conversion.
