Need a Regular expression to remove a char for Unicode text

[శ్రీనివాస]

Hai friends,
Can any one tell me how can i remove a character from a unocode text.
కల్‌&à° ¹à°¾à°° is a Telugu word in Unicode. Here i want to
remove '&' but not replace with a zero width char. And one more thing,
if any whitespaces are there before and after '&' char, the text should
be kept as it is. Please tell me how can i workout this with regular
expressions.

Thanks and regards

Don't know anything about Telugu, but is this the approach you want?

>>x=u'\xfe\xf f & \xfe\xff \xfe\xff&\xfe\x ff'
>>noampre = re.compile('(?< !\s)&(?!\s)', re.UNICODE).sub
>>noampre('', x)

u'\xfe\xff & \xfe\xff \xfe\xff\xfe\xf f'

The regular expression has negative look behind and look ahead
assertions to check that there is no whitespace surrounding the '&'
character. Each match then found is then replaced with the empty string

Can any one tell me how can i remove a character from a unocode
text. కల్<200c> &హార is a Telugu word in Unicode. Here i want to

text should be kept as it is.

So basically, you want to match <200c>& and replace it with <200c>,
but only if it's not surrounded by whitespace, right?

r"(?<!\s)\x200c &(?!\s)" should match. I'm sure you'll be able to take
it from there.

He wants to replace & with zero width joiner so the last call should be
noampre(u"\u200 D", x)

Pardon my poor reading comprehension, OP doesn't want zero width
joiner. Though I'm confused why he mentioned it at all.
