There are multibyte string functions in PHP to handle multibyte string (e.g:CJK script). For example, I want to count how many letters in a multi bytes string by using len
function in python, but it return an inaccurate result (i.e number of bytes in this string)
japanese = "桜の花びらたち"
print japanese
print len(japanese)#return 21 instead of 7
Is there any package or function like mb_strlen in PHP?
Use Unicode strings:
# Encoding: UTF-8
japanese = u"桜の花びらたち"
print japanese
print len(japanese)
Note the u
in front of the string.
To convert a bytestring into Unicode, use decode
: "桜の花びらたち".decode('utf-8')
Try converting it to unicode
first:
print len(japanese.decode("utf-8"))
gives 7. You are working on the utf-8 encoded string, which indeed has 21 bytes.
