Please answer these questions before submitting your issue. Thanks!

What did you do?

wrote a small function with unexpected results
see https://play.golang.org/p/1YFPR3ShVUx

the 2 lines in main() are identical except for the writing of "SpeciMen40" and "Specimen40"

str := "enum('Quader','Irregular','SpeciMen40','Type1','Type2')"
fmt.Println("return: ", trimTypeString(str))

str = "enum('Quader','Irregular','Specimen40','Type1','Type2')"
fmt.Println("return: ", trimTypeString(str))

If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
A link on play.golang.org is best.

---> https://play.golang.org/p/1YFPR3ShVUx

What did you expect to see? same result for both runs of the function

What did you see instead? different resuts

TrimRight doesn't do what you think it does. See the example at https://golang.org/pkg/strings/#TrimRight. You are almost certainly looking for TrimSuffix.
