I have completed the translation of the strings for Japanese.
But, I found that some HTML tags disappear after saving the translation.
Some strings including HTML tags, and the tags and parameter values in tags disappear, in particular,
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">
<html><head><meta name="qrichtext" content="1" /><style type="text/css">
Going forward, we’ll try to avoid using HTML formatting in translatable text, by adding formatting outside the translatable strings wherever it is possible.
I checked the Japanese translation on Weblate. I have done the replacement of the < > and so on to the original charactors and copying the html tags which are included in the origianl English strings to the translated strings.
