msLayoutTextSymbol replaces WRAP char unconditionaly with SPACE #5612

The "new" msLayoutTextSymbol function replaces all occurences of the WRAP character with a SPACE character and then wraps labels at these characters if they are longer then MAXLENGTH. For example, if you use WRAP '-' the label My-label-with-dash is rendered as My label with dash even if the label is not wrapped.

This appears to be a regression with MapServer 7. (/cc @tbonfort)

Is there a reason for this behavior? My understanding is that we can remove:


Lines 534 to 540 in 2b9d022

if(ts->label->wrap != ' '){
for(i=0;i<num_glyphs;i++) {
/* replace all occurences of the wrap character with a space */
if(glyphs.unicodes[i]== ts->label->wrap)
glyphs.unicodes[i]= ' ';

and replace the checks for ' ' with ts->label->wrap at these positions:

if(glyphs.unicodes[i]== ' ')

if(glyphs.unicodes[i]== ' ' && num_cur_glyph_on_line >= ts->label->maxlength) {

I can provide a patch, but please consider my follow up issue.
