<div dir="ltr">I would guess probably because Erlang uses ISO/IEC 8859-1, in which 155 is not defined while the others all are (<a href="http://en.wikipedia.org/wiki/ISO_8859-1#Codepage_layout" target="_blank">http://en.wikipedia.org/wiki/ISO_8859-1#Codepage_layout</a>). Characters between 137 and 159 are excluded, while all the rest are printable included.<br>

<div>OK. Then I 'll take a look at it io_lib.erl. But one more question: why the value 155 is unprintable while 228 is , considering they are both greater than 128.</div>

<div>Thanks.<br><br></div>

<div>I have a utf8 encoded file y.erl: the source is :</div>

<div>I don't know why they are outupted in diffrent format, one is string-format, the other is list-format. Why aren't they birth outputed in string-format or both in list-format?</div>
