P.S. The reason I originally used 0 to 90 was this line in the MAQ page and the
fq_all2std.pl text:

"In the quality string, if you can see a character with its ASCII code higher
than 90, probably your file is in the Solexa/Illumina format."

They do say "probably", so perhaps 91, 92 and 93 can validly occur. It might
help to know where your apparently very high quality FASTQ file came from.
