Line 9:
Examples need to use non ascii chars into code, but the lang tag does not permit it... so that møøse looks like møøse ... I've fixed wørld in AWK just because it showed an example from command line, where pre tag is reasonable... but it is not so for J e.g., where back to pre from lang tag would just be... a step back as said... Shouldn't exist a strange way to fix it? (I believe it is enough to allow UTF-8 encoding in lang tag... keywords are mostly ASCII, just APL should be checked... in fact, how does APL encoding work?) --[[User:ShinTakezou|ShinTakezou]] 23:05, 16 April 2009 (UTC)
: Likely a GeSHi bug. I'll drop them a line. --[[User:Short Circuit|Short Circuit]] 06:15, 17 April 2009 (UTC)
== Component Pascal ==
The example for character length does not deal with utf-8 and as much as I understand also fails with Non-BMP code points.
== Incorrect ==
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)
:: could we see a text file that contains the various BYTE strings and the expected length results? ..[[User:Walterpachl|Walterpachl]] ([[User talk:Walterpachl|talk]]) 08:03, 30 August 2014 (UTC)
== PL/I error ==
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.
