There is another solution to this problem (from Neil Soiffer
<soiffer at wolfram.com>):
In TraditionalForm, you can close off '{' with \[AutoRightMatch] (or
ESC\right.ESC)
to keep things properly bracketed. (This won't work for StandardForm unless
you set
DelimiterMatching->None for the cell (or larger scope).)

Again from Neil: Because very large brackets and braces for
their common uses in Mathematica (function call, lists) can look silly,
in UnicodeFontMapping.tr they are set to grow to at most '2.01'
(factor of two, with a fudge factor for sloppy arithmetic)
their normal size when SpanMax is set to Automatic. You can set
SpanMax around the character, at the cell level, notebook level,
or globally. You may not be happy with what the brackets and braces look
like for function call and lists though.
You could also change the value in UnicodeFontMapping.tr, but then handing
the notebook to someone else and having them see the large brace would
also require you handing them modified UnicodeFontMapping.tr, AND it would
allow all list braces to grow large.
Cheers,
Paul
