The byte length calculations for unicode appear generally incorrect. They're only valid for codepoints which are in the Basic Multilingual Plane, but not for the Supplemental planes. I.e. 🀁 wouldn't fit within a single wide character; it would be represented in UTF-16 as 0xD38C and 0xDC01 (if I've done the math right). --[[User:Short Circuit|Michael Mol]] 18:24, 15 March 2012 (UTC) |

: If you want to be completely general, there exist [https://en.wikipedia.org/wiki/Unicode_normalization other issues to consider.] Note, in particular, that not all combining forms have codepoints. --[[User:Rdm|Rdm]] 18:31, 15 March 2012 (UTC) |

the last line ( put skip list ('Byte length=', length(trim(SM)); ) |

<br>is syntactically incorrect (a closing parenthesis is missing) |

<br>I tried to add it and get an error message: |

<br>IBM1569I S 9.0 SIZE argument must be a CONNECTED reference. |
