File reading issue from application server in sap

Hi Experts,

We are facing issue while reading the data from application server file. But whenever we are reading the same file from desktop we are not facing any issues.

Ex data from file:109KRW123456

the above data is splitting as 10    9KR  W123456

but the correct splitting is 109  KRW 123456

Here my doubt is why data is moving by 1 place from 2nd character onwards.

Note:File format is UTF-8.

Code used:OPEN DATASET v_source_file IN TEXT MODE FOR INPUT ENCODING DEFAULT.

We have some other files in UTF-8 format with successful reading.

Please suggest me how to avoid this issue.
