# sasl_utf8verify - Verify a string is valid utf8

## Synopsis

    #include <sasl/saslutil.h>

    int sasl_utf8verify(const char *str,
                        unsigned len);

## Description

`int sasl_utf8verify(const char *str,`
`unsigned len);`

  Use the sasl_utf8verify interface to verify that a string is valid UTF‐8 and does not contain NULL, a carriage return, or a linefeed. If len == 0, strlen(str) will be used.

  Parameters:

  - str – A string.
  - len – The length of the string. If len == 0, strlen(str) will be used.

## Return Value

SASL functions should return SASL return codes. See sasl.h for a complete list. `SASL_OK` indicates success.

Other return codes indicate errors and should be handled.

- `SASL_BADPROT`: There was invalid UTF8, or an error was found.
