Hi, I found that at some of the ways (which have a filled REF-field) the highway-symbol is dropped and only the content of "REF" is shown. some examples(i used r1344). I write "_" instead of "real" spaces just to make it easier to read: if "B" is given the result is "B" "B1" instead results in "~[0x06]B1" (where ~[0x06] represents the highway shield) "_B_" surprisingly ends up in "~[0x06]_B_" "BW" results in "BW" "BW1" results in "BW1" "B_W1" results in "~[0x06]BW1" "BW;1 " results in "~[0x06]BW;1" "BW_1" results in "~[0x06]BW1" (ok, afaik intermediate spaces has to be removed, otherwise only the first part is visible in highway shield) I (like also people do in OSM database i saw) use the REF in combination with the highway shield also as marker for trails (in hiking/biking overlays) and therefore this behaviour disturbs. I have looked in the code and found in the HighwaySymbolFilter.java this "alpha_balance" which is the reason for. Simply changing "return value" to "return prefix + value" stops this. Looking at the examples, the results of the filter is a bit strange to me. I can't get the intention. Do we really need this filter ? cheers Gert
