Description

Hi, I'm using Redmine ver.3.4.7 and multi-byte environment(Japanese).

I found a bug in mail notifications function.
When I update a ticket with the comments below

-----
aaa<bbb>ccc
AAA<BBB>CCC
-----

The less-than sign, grater-than sign, and multi-byte "BBB" are deleted in the mail, while the ticket itself is properly updated.
Note that the first sentence is written using single-byte characters, and the second one is written using multi-byte characters except less-than sign(<) and grater-than sign(>).

It will not happen when the letters are quoted with < pre > and < /pre >.
Neither It will not happen when html mail is not used.

See the attached for details.

Maeda-san,
Thanks for prompt response and trying to reproduce.

I forgot saying this but if characters are all single-byte in < and >, the bug will not happen.
It happens only when the characters include multi-byte characters.

Please try using my sample in description section.

aaa<bbb>ccc
AAA<BBB>CCC

Actions #5

Updated by Yuichi HARADA about 5 years ago

Escape processing of "<" and ">" is performed by RedCloth3#escape_html_tags .
source:/trunk/lib/redmine/wiki_formatting/textile/redcloth3.rb#L1218

However, full-width characters could not be processed because they do not match the regular expression "\w".
Change the regular expression "\w" to "_" and "[[:alnum:]]" to match even full-width characters.

I attached the patches.
