Alphanumeric check — lots of false positives


as seen below, alphanumeric mismatch check introduces an awful lot of false positives, which makes this control virtually useless to me. I understand that this may be difficult to avoid algorihmically, but maybe something like a whitelist would do…?


The issue is caused by a wrong decision to include the dash as part of an alphanumeric word. The idea was to make the Alphanumeric Check find issues such as BW54A-A in source and BW54A-B in target, which was not detected by the previous algorithm.

As I said, the decision to include the dash was wrong because some language include dashes intensively in regular words, so it will be reverted in next Xbench update.

Do you think you could also add skipping checks when the „alpha” part of alphanumeric string strongly indicates that this is a value of something and the unit, like 30Hz? I’ll always be getting lot of false positives here, because Polish requires me to insert a space between the number and the unit.

We try to avoid false positives with a few UoM, but it seems that we forgot to include Hz as a UoM. We’ve now included it and should be fixed in the next Xbench update, thank you for reporting it.

I’m also getting false positives for “x” used as a multiplication sign, e.g. Frame, 10x mini rollers and tray (280 x 150 x 55mm, sometimes together with other UoMs, e.g. 20mm; 2x30mm; 40mm; 50mm Round

This is also a false positive for target, for Polish:

Alphanumeric Mismatch Target (4-CZĘŚCIOWY)
Diall Fine Finish 4 Piece Mini Roller Set

— it’s a typical way to write that sth consists of a number of pieces/elements.

And another false-positive-triggering unit: V.

I still keep getting lots of f.p. within alphanumeric mismatch for English ordinal numbers, like 1st, 2nd etc. Would it be possible to eliminate those from the check too?
