doc: avoid unicode errors in texi conversion

Browse Source 
Avoid "Unicode character U+#1 not supported, sorry" error
when converting from texi to dvi or pdf.

* doc/coreutils.texi (tr invocation): Avoid the @U{XXXX}
texi representation, as even though info and html can represent
these characters directly, there are conversion errors
for pdf and dvi.  Instead use the more abstract shell
$'\uXXXX' representation.

@ -6972,7 +6972,7 @@ The interpretation of @var{string1} and @var{string2} depends on locale.
GNU @command{tr} fully supports only safe single-byte locales,
where each possible input byte represents a single character.
Unfortunately, this means GNU @command{tr} will not handle commands
like @samp{tr @U{7530} @U{68EE}} the way you might expect,
like @samp{tr $'\u7530' $'\u68EE'} the way you might expect,
since (assuming a UTF-8 encoding) this is equivalent to
@samp{tr '\347\224\260' '\346\243\256'} and GNU @command{tr} will
simply transliterate all @samp{\347} bytes to @samp{\346} bytes, etc.
