If an attempt is made to encode a string to octets using an encoding that does not support some of the characters in the string, the result should be an error, but is in fact a bogus byte vector, e.g.:

? (encode-string-to-octets "(λ (μ) μ)" :EXTERNAL-format :ascii)
#(40 26 32 40 26 41 32 26 41)

I'm an average level Common LISP user/programmer, not familiar with the environment's internals, using

• CCL Version 1.11.1 (16714) downloaded 05/19/2017 from Apple's App Store
• MacOS Sierra 10.12.5 (16F73)

I use a $HOME/ccl-init.lisp file to load other personal files upon CCL double-clic startup. I use the Macintosch IDE. My cl-init.lisp file allows me to choose between a couple of (load #P"/blabla...") forms. My personal files are loaded indeed, but leading to strange behaviors. In all cases, the following fixes the problem(s):

1. open the concerned file(s) in editor window(s) (i.e. File menu > Open...)
2. re-evaluate the whole file(s) (i.e. <cmd><shift><E>) or appropriate part(s) of it (i.e. <cmd><E>)

From then on, things work properly. It's as if the files had been first carelessly loaded upon startup, some elements skipped or something of that sort... (I know this is absurd.)

Example 1 A class defined in a file loaded by cl-init.lisp is defined indeed (it's not reported as undefined), but with one of its slots missing or bugged: the slot's initarg is reported invalid. It's fixed as soon as I re-evaluate manually the defclass source code.

Example 2 A function is defined (not reported as undefined), but gives wrong results when called (details not significant). It's fixed as soon as I re-evaluate manually the defun source code.

Example 3 A function is defined (not reported as undefined), but gives this error when called:

> Error: The value NIL is not of the expected type NUMBER.
> While executing: CCL::+-2, in process Listener(5).

Similar issue in LW (Lispworks)? Example 3 seems to me similar to the following error when opening a file with my older LW 6.1 in the newer MacOS Sierra 10.12.5:

 Error in process "Cocoa Event Loop" {undebuggable process}
 In + of (NIL 0) arguments should be of type NUMBER.

In LW 7.0, I have learned from experience with an Evaluation license that the latter bug and other oddities are somehow fixed within four (pre compiled) files in the private-patches folder. However, I'm switching to CCL to avoid purchasing LW 7.0, aside from the pleasure of going back to an environment similar to MCL, which I used a lot until 2008 on Motorola Macs, and liked very much.

Tentative causes

• Problem between CCL and Cocoa in MacOS Sierra 10.12.5? (I'm afraid I have only a vague idea about what Cocoa really is in fact...)
• Differences (ex. character set) between files as stored on disk and once opened in editor window buffers?

Sorry for the lengthy report!

Mac App store CCL is still version 1.8.
