// Strips HTML/XHTML to a plain text + ESC-token string suitable for rendering.
|
|
//
|
|
// Output format:
|
|
// - Every paragraph begins with an alignment token: ESC + 'L'|'C'|'R'
|
|
// - Paragraphs are separated by '\n\n'
|
|
// - Single '\n' = line break within a paragraph
|
|
// - Bold/italic spans are bracketed by ESC tokens (for future span rendering):
|
|
// ESC+'B' = bold on, ESC+'b' = bold off
|
|
// ESC+'I' = italic on, ESC+'i' = italic off
|
|
// - All inline ESC tokens are 2 bytes (ESC + code); renderers that don't
|
|
// support inline styles strip them before setting label text.
|
|
//
|
|
// HTML handling:
|
|
// - <h1>/<h2> → center aligned; <h3>-<h6> → left aligned
|
|
// - <p>, <div> with style="text-align: center/right" → center/right aligned
|
|
// - <b>, <strong>, <span style="font-weight:bold"> → bold on/off tokens
|
|
// - <i>, <em>, <span style="font-style:italic"> → italic on/off tokens
|
|
// - <br> → '\n'
|
|
// - <li> → '\n- ' prefix
|
|
// - <style>, <script>, <head> blocks suppressed entirely
|
|
// - All HTML entities decoded; multi-byte UTF-8 passed through
|
|
// - ­ → U+00AD soft hyphen (LVGL respects this for line breaking)
|
|
// - Typographic entities (—, ‘ etc.) → proper Unicode
|
|
// - Liang hyphenation applied to ASCII words (English, with soft hyphens)
