Minor Composers - some problems I am struggling with!

[pgbj]

First, let me say this is a cracking bit of software and with any other software I wouldn't probably be able to even attempt to do this. So thanks!

I have a moderate-sized classical music library which I mainly search as COMPOSER->CATEGORY("Oratorios","Piano Sonatas"etc)->COMPOSITION or ALBUM. Due to a few compilation-type albums, my list of composers has "Bach" (100+ albums) shoulder-to-shoulder with "Banchieri" (1 madrigal on a re-construction of Venetian Vespers). So I decided to do the following to "remove" these minor composers from my main index...

Set up a tagUpdate file with entries such as:

@COMPOSER=Banchieri
=COMPOSER=[Minor Composers]
+MINORCOMPOSER=Banchieri

then in the tagValues property (and MinorComposer in itemTags):

Composer.value.display={MinorComposer}

The idea being I would just get a catchall [Minor Composers] entry in the index but would still see the composer or minor composer name if set in the Now Playing screen (or wherever Bubble deigns to display it).

1. The tag update all seems to be happening and is recorded in a tag update file. The minor composers are gone from the index and replaced by a single [Minor Composers]. However, the MinorComposer tag does not seem to be replacing the composer display value. Instead I get [Minor Composers] displayed as the composer metadata in Bubble. If I for example add MinorComposer to indexTags I see a list of minor composers so that all works.

2. I have a couple of composers with accents e.g Albéniz. I think this is all entered UTF-8 but it does not show any match in the tag update log. Should this be able to match? It displays properly everywhere.

3. I chose the catchall [Minor Composers] as I thought square brackets would sort after alphanumeric in UTF-8 and so be at the end of the index. Instead it is at the front?

Any thoughts? Thanks!
