In Well Known NDEF records of RTD "Text", the first byte in the payload is the status byte. This byte contains, according to the spec:

bit number (0 is LSB)	Content
7	0 for UTF-8, 1 for UTF-16
6	RFU (MUST be set to zero)
5..0	The length of the IANA language code.

So it is not 5 bits, but bits 5 to 0.
