Correct charset for |

I'm printing some text using a thermal printer. Everything works fine, except when I try to print the vertical bar character | my printer shows Ö, so I think that the error is in this part:

text=msg.getBytes("UTF8");

But I don't know why; if I'm using the UTF-8 charset, it seems like it should work. What's wrong?

I've tried it with ("UTF-8"), ("UTF8"), ("ISO8859-1"), ("ISO88591"), ("ISO-8859-1"), but the same thing happens with each.

UPDATE

This is what I like to print (In an Android device) enter image description here

And this is what I'm getting ont he printer enter image description here

It looks like your thermal printer is configured to use one of the ancient character encodings where "uncommon" characters - brackets, braces, vertical bar, .... - are replaced by "national characters," for example ä, ö ü and ß in Germany. When the device is set to use these encodings there is no way to output the replaced characters.

Have a look at the user manual for the thermal printer. There must be a way to change the character mapping to standard ASCII. The Linux console for example has the escape code "\033(B" to return to the usual ASCII encoding.
