#518 closed defect (fixed)

[PATCH] Unicode normalization

Reported by: moyogo@… Owned by: framm
Priority: minor Milestone: 14.01
Component: Core Version: latest
Keywords: Cc:

Description (last modified by Don-vip)

JOSM should normalize strings at input. They should also be normalized when searching.

For example inputing name="Rue de l'École" should end up the same as name="Rue de l'École". The first has "É" as U+0045 LATIN CAPITAL LETTER E + U+0301 COMBINING ACUTE ACCENT while the second has "É" U+00C9 LATIN CAPITAL LETTER E WITH ACUTE.
Searching for one should match the other.

See ​http://unicode.org/faq/normalization.html for more info.

java.text.Normalizer.normalize(string, java.text.Normalizer.Form.NFC) can be used when required.
NFC is probably better because it's better supported than NFD due to legacy.

Normalization has been reverted in r1168 but only partially restored in r3556.

Entering name="Rue de l'École" or name="Rue de l'École" do not produce the same result, even if both are found thanks to search compiler.
