That's why there's a string_get_match() function in strutils.sl that does
this.

It's in the tm documentation for substr():

NOTES
   In many cases it is more convenient to use array indexing rather
   than the `substr' function.  In fact, if UTF-8 mode is not in
   effect, `substr(s,i+1,strlen(s))' is equivalent to
   `s[[i:]]'.  Array indexing uses byte-semantics, not character
   semantics assumed by the `substr' function.

String_get_match() uses substr(), so it should be all right.
