 ### String Truncation ### {#sctn-strings-truncation}
 
-Each arbitrary string in the API will have some accommodation for the potentially limited resources available to an [=authenticator=]. If string value truncation is the chosen accommodation then authenticators MAY truncate in order to make the string fit within a length equal or greater than the specified minimum supported length. Such truncation SHOULD also respect UTF-8 sequence boundaries or [=grapheme cluster=] boundaries [[UAX29]]. This defines the maximum truncation permitted and authenticators MUST NOT truncate further.

 For example, in <a href="#fig-stringTruncation">figure <span class="figure-num-following"></span></a> the string is 65 bytes long. If truncating to 64 bytes then the final 0x88 byte must be removed purely because of space reasons. Since that leaves a partial UTF-8 sequence the remainder of that sequence may also be removed. Since that leaves a partial [=grapheme cluster=] an authenticator may remove the remainder of that cluster.
