Getting the BYTE size of a string

[ESPsupport]

33 is the length/size in bytes.

Do you need to use str_Ptr around your string address (str_Length() expects a string pointer)?

Hi
I need to know how to get the size of a string in bytes, the string is stored in a buffer[100]. I can get the length of the string using str_Length(), which results in 33.
but i need the size of the string in bytes, please.
