wierd characters when displaying content of file

[maciek4]

I have a txt file and when I display the content using echo some lines display correctly and some have wierd characters in between letters:

for example:

<?php
echo $lines[1];
echo $lines[2];

as a result I am getting correctly displayed first line:
1st line: Product A
2nd line: between each letter there is a square P(square)r(square)o(square)d(square) etc.

What should I do to display it correctly and why is it doing that?

try opening your textfile in NOTEPAD and seeing if the boxes are showing in that. if they are.. delete them using notpad.

boxes are normally hidden characters that cant be seen in some programs, but others dont understand what the characters are so they output a box. at least... thats what im lead to believe.
