Concatenate character encoding issue

I have the following code:

(setf dirname

(concatenate 'string

(coerce dirname 'text-string)

(coerce dp ‘text-string) "/"))

I get the following error with a certain directory input name:

Error: #\– (of type CHARACTER) is not of type BASE-CHAR.

The filename is: BLADE X3 WORKStation – SUSE Studio,1_files

The ‘dp’ is coming from the result of #’pathname-directory.

‘dirname’ is simply the result of concatenating the dp parts together with a “/“.

Any suggestions to help deal with this character range encoding issue?

Hi Burton,

Have a look at http://www.lispworks.com/documentation/lw70/LW/html/lw-191.htm ,
which explains the various string and character types in Lispworks 7.

I guess the summary is: it helps to use CHARACTER as your default character
element type, e.g.

   (set-default-character-element-type 'character)

Re: Concatenate character encoding issue

Clarification: your minus character is not an ordinary ASCII minus, so
it does not belong to base-char.  For sure you can check it with
char-code.

If you need such chars (e.g. you do not generate them yourselves), use
Lemmens suggestion about changing default character set.

Re: Concatenate character encoding issue

Hi,

you have coerced the strings to type LW:TEXT-STRING.

Then it would be a good idea to use this type in CONCATENATE, too:

(concatenate 'text-string ...)

Documentation:   text-string is the type of strings that can hold any character...

Regards,

Rainer
