Converting from Array[String] to Seq[String] in Scala

Question

In the following Scala code I attempt to convert from a String that contains elements separated by "|" to a sequence Seq[String]. However the result is a WrappedArray of characters. How to make this work?

val array = "t1|t2".split("|")
println(array.toSeq)

results in:

WrappedArray(t, 1, |, t, 2)

What I need is:

Seq(t1,t2)

The below works. ie split by pipe character ('|') instead of pipe string ("|"). since split("|") calls overloaded definition that takes an regex string where pipe is a meta-character. This gets you the incorrect result as shown in the question.

scala> "t1|t2".split('|').toSeq
res10: Seq[String] = WrappedArray(t1, t2)
