How about this?

B4X:

Dim value As String = "h" & txtHLThigh.Text
astream.Write(value.GetBytes("utf8"))

Another option which is relevant when you want to append raw bytes is to use B4XBytesBuilder from B4XCollections. It is similar to StringBuilder but works with arrays of bytes.

Or maybe (harder to read though)

B4X:

astream.write(("h" & txtHLThigh.Text).As(String).GetBytes("utf8"))
