tags 597665 + patch kthxbye I've attached a patch which solves the problem by marking tabs with spans with class "tab".
This patch is necessary because there are two contexts in which HTML can be generated: CSS-ignoring and CSS-supporting. In the former, tabs will never be displayed properly. However, the only way to create appropriate line breaks is via the br tag, because using the white-space CSS property won't work (since CSS is not supported). In CSS-supporting contexts, we *can* get sane white space handling, including for tabs, by using white-space: pre. Unfortunately, with the br tags, this causes two line breaks, which makes every line double-spaced. Since we need the br tags for the CSS-ignoring case, the only way to handle tabs correctly involves using a span to allow styling of the CSS. We don't need to handle any other characters specially since white-space handling in CSS is limited to space, tab, carriage return, and linefeed. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
