Special characters
ASCII
The following ASCII codes are recognized:
{NUL}, {SOH}, {STX}, {ETX}, {EOT}, {ENQ}, {ACK}, {BEL}, {BS}, {HT}, {LF}, {VT}, {FF}, {CR}, {SO}, {SI}, {DLE}, {DC1}, {DC2}, {DC3}, {DC4}, {NAK}, {SYN}, {ETB}, {CAN}, {EM}, {SUB}, {ESC}, {FS}, {GS}, {RS}, {US}
In addition to these, {TAB} can be used as an alias for {HT}.
Unicode
Unicode characters can be inserted using {U+nnnn} where nnnn is the hexadecimal Unicode, e.g. {U+20AC} for the Euro symbol (€), or {U+1B} which is equivalent to {ESC}.
Non-breaking space
The code {NBSP} is used to insert a non-breaking space, i.e. a space that is not used to break lines.
