Composers with non-numerical identifiers

I've discovered some composers on Musicalics whose identifier do not fit the formatter URL pattern. Examples:

Armine Abrahamyan (Q107303627): https://musicalics.com/en/composer/Armine-Abrahamyan
Vincenzo Palermo (Q4013444): https://musicalics.com/en/composer/Vincenzo-Palermo
Gunther Schuller (Q704154): https://musicalics.com/en/composer/Gunther-Schuller

However, IDs for other composers remain numeric, for example, Alan Hovhaness (Q542232): https://musicalics.com/en/node/79910

How can we accommodate two different types of URLs for composers in this database? UWashPrincipalCataloger (talk) 01:31, 21 June 2021 (UTC)
