Log Message:
Unicode @-codes: return the expansion instead of printing it

@U+XXXX@, @CHECKMARK@, @ELLIPSIS@, @COPY@, @SOUNDCOPY@, @REGISTERED@, @TRADEMARK@, @DEGREE_C@, @DEGREE_F@ and @WIDE:text@ wrote their glyph
straight to the terminal from inside atcode() and returned an empty
string. Format modifiers were therefore applied to "": @CHECKMARK-R10@
emitted the glyph and then right-aligned nothing in a 10-column field.
Callers that expand an @-code into a buffer for a non-printing reason -- bbs.atcode(), bbs.expand_atcodes(), format_text(), mnemonics(),
putnode(), notify() and putmsg()'s @CENTER@ -- got an empty expansion
plus stray output on the current node's terminal.

These codes now encode into the caller's buffer and set P_UTF8, so show_atcode()'s existing display-width compensation makes alignment and truncation work. formatted_atcode() and expand_atcodes() take an
optional pmode out-param so the buffer-expansion callers can learn the
result is UTF-8; @CENTER@ and mnemonics() use it, the latter needing the
P_UTF8 branch bputs() already has, since it emits byte-by-byte through outchar(). Terminal::center() measures with bstrlen(str, mode & P_UTF8):
the other code sets bstrlen() recognizes are translated by putmsg(), not bputs(), and a centered line bypasses putmsg()'s character loop.

The |W (doubled) modifier prints a UTF-8 expansion as-is rather than
feeding it to wide(), which would double each byte rather than the glyph. Output buffers grew to fit @WIDE:, which triples byte length.

Introduced in 9374bfe37e (pill-4-pencil), a9eea57362 (begun-3-ended) and 43c793a14b (hold-20-maps).

Fixes #1198
