The various alternate Greek letter shapes (curly beta, curly rho, "script"
kappa, etc.) were put in Unicode because they were present in pre-Unicode
character sets. They really don't belong in Unicode because they do not
follow the encoding model that Unicode is based on (encoding characters not
More important, these characters should be used with great caution, if at
all. Consider the fact that if a user searches a document for the word
"biblion" and types a standard beta at both positions, he won't find the
word if it is encoded using the "curly" beta in the middle. The same
problem applies with all the other glyph variants (except those specifically
designed for mathematical use, which may be used in math). If one is
preparing a text only for printing on paper, this is not an issue of course;
but given how often texts are used used in multiple ways these days, I feel
strongly that it is best to avoid using any of the alternate Greek forms.
(Consider, for example, that a document in PDF form may be printed, read on
screen, or searched.)
The best way to get alternate letter shapes is to use advanced font
technologies such as AAT or OpenType that allow the display of alternate
glyphs without modifying the underlying Unicode values.
I know that support for these technologies is still limited, but it is
improving and will probably be more widespread with the next release of
Windows, which will support OT features at the system level. If you want
more information about these technolgies, particularly with reference to the
needs of scholars, see the draft document I have posted at

The glyph may be changed, but whether it worth bothering with I am not sure,
given what I have said above.
