In Chrome, the terminal cells will grow in width when box-drawing characters are applied

[domsson]

For example, with the current font and font size, an empty cell (containing a space) is 10px in width, but as soon as we paint some box drawing character into it, it will grow to 12px in width. This makes the entire canvas/terminal "grow". Not great.

Actually, the same can happen in Firefox with some characters, like some pretty big Kanji that I recently put in a palette by accident.

One possible solution would be this dirty JS hack:

• go through the entire glyph palette, put each character in a dummy cell
• check the calculated size of the cell
• keep track of the largest cell
• apply that size to all cells

Don't like it at all, but would probably work.
