Re: About HTML unicode

HI all: 

 Thanks masanori's reply and sample code! Before i saw your emai, i did the 
job and it's indeed so easy. The only trick is to say "use utf8" and then 
ord and length etc. can correctly handle multibytes. 

 Now i encountered another problem,  there are a few files contains not only 
one charset but also two or more, for example, file1 contains japanese and 
chinese, if i use open() to  load the data into memory, ord and length etc.. 
can't correctly work! Perhasp i miss something to encode or decode the data 
? 

 code:
#!/usr/bin/perl -w
use utf8; 

open(FD, "< file1");
while(<FD>) {
chomp;
print "length = ".length($_);
}
close FD; 

 ----------
length() can not count the correct non-ASCII characters. :(
