Why does Python print unicode characters when the default encoding is ASCII?
...o compatible in that range.
e.g. Unicode code point for 'B' is '0x42' or 0100 0010 in binary (as we said, it's the same in ASCII). After encoding in UTF-8 it becomes:
0xxx xxxx <-- UTF-8 encoding for Unicode code points 0 to 127
*100 0010 <-- Unicode code point 0x42
0100 0010 <-- UTF-...
Using awk to remove the Byte-order mark
...
Try this:
awk 'NR==1{sub(/^\xef\xbb\xbf/,"")}{print}' INFILE > OUTFILE
On the first record (line), remove the BOM characters. Print every record.
Or slightly shorter, using the knowledge that the default action in awk is to print the record:
awk 'NR==1{su...

0xf84000f010 vs. 0x7f095ed0bf68
0xf84000f014 vs. 0x7f095ed0bf68
0xf84000f018 vs. 0x7f095ed0bf68
So the only thing you can do is to either use pointers or the index, as already proposed by jnml and peterSO.

Note that it has two parameters. The first is your function and the second is an implicit. If you do not provide that implicit, Scala will choose the most specific one available.
