[Lazarus] UTF8 string handling problem under linux

[Xiangrong Fang]

To help reproduce the problem, I altered the program a bit so that it does
not look for a folder containing CJK path.  To reproduce the problem:

1) compile and run this program under Linux (I am running Ubuntu 13.04
amd64).
2) Click the "Write" button and choose the included "test.txt" file.
3) Click the "Read" button, the program will crash.

Note: the test.txt file contains two lines, the program only read the first
line, if that line contains CJK, it will crash.

Thanks,
Shannon
