>From groff.info:
* A glyph for Unicode character U+XXXX[X[X]] which is not a
composite character is named `uXXXX[X[X]]'. X must be an
uppercase hexadecimal digit. Examples: `u1234', `u008E',
`u12DB8'. The largest Unicode value is 0x10FFFF. There must be at
least four `X' digits; if necessary, add leading zeroes (after the
`u'). No zero padding is allowed for character codes greater than
0xFFFF. Surrogates (i.e., Unicode values greater than 0xFFFF
represented with character codes from the surrogate area
U+D800-U+DFFF) are not allowed too.
[...]
Note that this mechanism won't work for (printable) ASCII characters,
which you still have to use as-is. If you use UTF-8 as a Unicode
representation, all characters longer than a single byte can be
converted to the \[uXXXX] representation form.
On the other hand, there is no longer a need to do this manually:
groff comes with `preconv', a preprocessor which can convert virtually
any encoding (using the `iconv' function) to \[uXXXX].
