As stated by [~alanb][1], the naming of `JavaLangAccess::*NoRepl` methods has confused several people as not everyone is familiar with coding error actions. Here, "no replacement" actually means that coding errors are reported. Following [~rgiulietti]'s suggestion[2], this issue requests renaming those methods to `*NoReplacementChar` instead.
