Environment

Release : Any

Component : Spectrum Core / SpectroSERVER

Cause

Spectrum having an issue with non-ascii characters

Resolution

Use the following to look for non-ascii characters and correct:

1. Run the Modeling Gateway export

    a. Log into the SpectroSERVER system as the user that owns the Spectrum installation

    b. If on Windows, start a bash shell by running "bash -login"

    c. cd to the $SPECROOT/SS-Tools directory and enter the following command where <VNM> is the hostname of the SpectroSERVER system:

./modelinggateway -vnm <VNM> -e MG_Export

2. Review the MG_Export.xml file for any non-ascii characters.

NOTE: A couple of non-ascii characters known to cause this issue are "ñ" and "ö"

Additional Information

For Spectrum 21.2.8 patch Spectrum_21.02.08.D183 has been created to prevent the crashes with accented characters.

For Spectrum 22.2.8 patch Spectrum_22.02.08.D189 has been created to prevent the crashes with accented characters.

 

If you are not sure, you can use the regular expression "[^\x00-\x7F]+" to look for non-ascii characters in the MG_Export.xml file.

For example:

1. Go to https://regex101.com/

2. Enter [^\x00-\x7F]+ in the REGULAR EXPRESSION field

3. Enter your text string from the MG_Export.xml file in the "TEST STRING" field

4. Matches will be displayed in the MATCH INFORMATION field
