Generally no problem, I believe.
In many cases Perl 5.8.x properly treats a string value with UTF8-flag
turned on and a string value with UTF8-flag turned off.
But your original script is for perl 5.005_03, in which the UTF8-flag
is not implemented. Such an old script might contain some operation
or function whose behavior has been changed between perl 5.005_03
and perl 5.8.7. Possibly something which were not distinguished
each other might be distinguished now unexpectedly.
If something is found problematic, you can use
utf8::downgrade($value) to turn the UTF8 flag off safely.
