 You can also change the indentLine char:  
 for both Vim and GVim, set `let g:indentLine_char = 'c'` where `'c'` can be any ASCII character. You can also use one of `¦`, `┆` or `│` to display more beautiful lines. However, these characters will only work with files whose encoding is UTF-8.
 
+### Font patching
+If you find all the standard unicode and ASCII characters too obtrusive, you might consider patching your font with the [indentLine-dotted-guide.eps][glyph] glyph provided.  [FontForge][fontforge] makes the process amazingly simple:
+
+ 1. Download and install FontForge.
+ 2. Locate and open your terminal/gVim font.
+ 3. Open the font in FontForge, choose __Goto__ from the __View__ menu and select _Private Use Area_ from the drop down box.
+ 4. In the private use area, locate a blank spot for the glyph. Make a note of the code, e.g. `U+E0A3`.
+ 5. Double-click the selected code point to open the font drawing tool.
+ 6. From the __File__ menu, select __Import...__ and locate the _indentLine-dotted-guide.eps_ file.
+ 7. Once imported, choose __File__ -> __Generate Fonts__ and choose a location and file type for the new font.
+
+Once completed, your new font will contain the more subtle dotted guide and all you have to do is set that glyph to `g:indentLine_char` in your `.vimrc` file.
