New submission from Basil Peace: HTML pages inside CHM documentation use the following tag to set applied character set: <meta http-equiv="Content-Type" content="text/html; charset=iso8859_1" /> `iso8859_1` is neither valid character set according to IANA registry nor is recognized by most browsers (I've checked IE, Firefox and Opera). This isn't notable for text in English. But, in `Python Standard Library` in section `4.7.1 String Methods` there is a documentation for str.casefold(). This paragraph contains German letter `ß`. Without defined character set this letter can be displayed wrongly, depending on user's regional settings. In my Russian I see in CHM `Я`. Firefox displays it as `�`. Fix of charset to `ISO-8859-1` could resolve the problem. P.S. Use of UTF-8 may be more convenient for preventing future errors. ---------- assignee: docs@python components: Documentation messages: 195136 nosy: docs@python, grv87 priority: normal severity: normal status: open title: Invalid charset in HTML pages inside documentation in CHM format versions: Python 3.3 _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue18736> _______________________________________
